Why the Standard ConnectWise Migration Advice Fails
Every connectwise migration guide you'll find tells you to "clean your data first" and "get stakeholder buy-in." Thanks, very helpful. What they don't tell you is which data fields actually break things, what happens to the 47 open tickets sitting in ConnectWise on day 1 of go-live, or why your QuickBooks sync becomes a liability the moment you stop feeding it from your PSA.
This runbook is built for a 40-person MSP — roughly 6–10 technicians, 3–4 account managers, a finance person, and an ops lead — making a full stack switch to BrioSync (PSA + ITSM + Finance + CRM in one). The target is 60 days from kickoff to full cutover. Not 6–9 months. Sixty days is achievable for a firm your size if you stop treating this as an IT project and start treating it as a change management project with a tight technical checklist.
One real constraint to plan around: ConnectWise modified their API terms in 2024 to restrict direct data exports to competing platforms. That means you're working with CSV exports, not a slick automated pipeline. Build that time in.
The 60-Day Week-by-Week Runbook
Weeks 1–2: Audit and Data Mapping
Don't touch BrioSync yet. Spend these two weeks entirely in ConnectWise and QuickBooks, documenting what you actually have — not what you think you have.
What to export from ConnectWise (CSV):
- Companies + contacts (including all custom fields — these are the silent killers)
- Active agreements and SLA definitions
- Open and closed tickets from the last 24 months
- Time entries tied to tickets for the last 12 months
- Product/service catalog
What to pull from QuickBooks:
- Chart of accounts
- Open AR, unpaid invoices (the last 90 days at minimum)
- Historical invoice records you'll need for audit
- Vendor list and any recurring bills
Your data mapping doc should be a simple spreadsheet: column A is the ConnectWise/QB field name, column B is the BrioSync field it maps to, column C is any transformation logic (e.g., "Priority 1 in CW = P1/Critical in BrioSync"), and column D is your validation rule. Get your finance person and your most experienced tech to sit in the same room for a half-day to build this. Don't delegate it entirely to one person.
The hidden trap here: duplicate company records. The average MSP with 40 seats has been in ConnectWise for 5–8 years. You almost certainly have the same client listed under two slightly different names. Find them now. Merging dupes after import doubles the cleanup time.
Weeks 3–4: Configure BrioSync and Test Import
Now open BrioSync. Configure in this order: company structure → SLA tiers → service boards → agreement types → chart of accounts → user roles. Do not start importing real data yet.
Once configuration is done, run a test import with 10% of your company records and 50 historical tickets. Check three things specifically:
- Do SLA breach timestamps survive the import intact?
- Do time entries attach to the correct tickets and companies?
- Do agreement line items map cleanly to BrioSync's contract module?
If any of those three break, fix the mapping doc before importing anything else. This test cycle will surface at least two fields you forgot to map. That's normal.
For BrioSync's AI-native features, this is also when you set up your ticket triage rules and automation workflows — not after go-live. Getting AI triage tuned before you're live means your techs hit the ground running on day one rather than spending the first two weeks manually routing everything.
Week 5: SLA and Contract Cutover Planning
This is the week most PSA migrations skip, and it's the week most migrations quietly fail.
For every active client agreement, you need a cutover record that captures:
- Current SLA definition in CW (response time, resolution time, escalation path)
- Verified equivalent in BrioSync — don't assume the field names mean the same thing
- Renewal date — if a contract renews within 30 days of your go-live, handle it manually in both systems until you're stable
- Billing cycle — weekly, monthly, or milestone-based agreements need different handling during the transition window
For any client with an SLA that includes financial penalties for breach, flag them explicitly. These are your zero-tolerance accounts during cutover week.
This is also when you brief your account managers. They don't need a deep technical walkthrough — they need to know: which clients are moving when, whether their client-facing portal URL is changing, and what to say if a client asks why their invoice looks different next month.
Week 6: Historical Billing Reconciliation
This week is entirely finance. No new imports. No configuration tweaks.
Run a side-by-side reconciliation of the last 3 months of invoices between QuickBooks and ConnectWise. Match every line item. You're looking for:
- Time entries in CW that never made it to a QB invoice
- Credits issued in QB that don't have a corresponding record in CW
- Any agreement overages that were billed manually and aren't reflected in CW
This step routinely surfaces 2–5% of unbilled time at MSPs this size. That's real money. It's also your baseline: when you run the same reconciliation 60 days after going live on BrioSync, you'll see whether the unified billing module actually closed that gap.
Once reconciliation is clean, freeze QuickBooks. No new invoices go out of QB from this point. All new invoices generate from BrioSync and flow to your accounting layer via BrioSync's integrations. If your accountant insists on keeping QB as a read-only ledger during transition, that's fine — just make the freeze date explicit and stick to it.
Week 7: In-Flight Ticket Handling and the Parallel Run
This is your parallel week. Both systems are live. Every new ticket that opens goes into BrioSync. Every ticket already open in ConnectWise stays in ConnectWise until it closes. Do not migrate open tickets mid-stream — the SLA timestamp chaos alone will cost you hours of cleanup.
Your ops lead needs a daily reconciliation list during this week:
- How many tickets are still open in CW? (Should be shrinking daily)
- Are any CW tickets at risk of SLA breach before they close?
- Are any CW tickets owned by techs who've already fully transitioned to BrioSync?
For that last category — tickets in CW owned by techs now working in BrioSync — you have two options: reassign them to a "CW cleanup" queue managed by one designated tech, or duplicate-enter updates in both systems until close. The first option is cleaner. The second is lower risk if you're paranoid about ticket history gaps.
Target: CW ticket count at or near zero by end of week 7.
Week 8: Full Cutover and Post-Migration Audit
Go-live week. CW is now read-only for historical reference. QB is ledger-only. BrioSync is your system of record for tickets, contracts, billing, and client data.
The first 72 hours, have someone check three dashboards every morning:
- Open ticket queue — are SLA timers firing correctly?
- Contract module — do all active agreements show correct renewal dates and billing terms?
- AR aging — did the first BrioSync invoices generate with the right line items?
If anything is wrong in those three areas, you want to catch it before your clients do. By day 5, you're doing your first real BrioSync month-end prep. Your finance person should be able to run their billing reconciliation from a single platform for the first time — no QuickBooks tab, no ConnectWise tab, no Excel bridge.
For pricing context: your entire 40-person team runs on BrioSync Pro at $19.99/user/month — that's $799/month for the whole suite. Compare that to what you were paying for ConnectWise Manage licenses alone, plus ConnectBooster, plus QuickBooks, and the math usually closes fast.
Change Management: The Part That Actually Determines Success
The technical runbook above will work. What kills PSA migrations isn't the data — it's the three techs who keep logging time in ConnectWise for two weeks after go-live because nobody told them which system was live.
Do these four things:
- Name a migration owner who isn't the CEO. It needs to be someone with enough authority to make daily calls and enough time to actually check the checklists.
- Send a single-page brief to all staff at the end of week 6. What's changing, when it's happening, and what to do if something breaks.
- Run a 90-minute hands-on walkthrough for techs the Friday before go-live — not a slide deck, actual ticket creation and time logging in BrioSync.
- Build a Slack channel called #migration-issues that lives for the first 30 days post-launch. Low friction for surfacing problems. It also lets you document the fixes you make, which becomes your internal runbook for the next migration (or the next acquisition).
The teams that fail PSA migrations aren't the ones with bad data. They're the ones who underestimated how much their team had muscle memory for the old system. Budget for a productivity dip in weeks 7–9. It's normal. It doesn't mean you picked the wrong platform.
