Switching Your Team to One Tool in a Week

Consolidating three or four tools into one sounds like a project that takes a quarter. It doesn’t have to. Most of the actual work — exporting data, re-creating structure, retraining habits — fits into a focused week if you sequence it right. Here’s the playbook we’d follow with any team, using Proman as the worked example, but the sequence applies whatever tool you’re moving to.

Day 1: Audit Your Stack

Before you touch anything, write down what you actually have:

Every tool currently in use, including the ones nobody officially approved (that shadow Trello board someone’s been running).
Every active project, and which of those are genuinely active vs. dormant. Be honest — a project with no activity in 60 days doesn’t need a clean migration, it needs an archive.
Every integration currently wired between tools (Slack notifications from your PM tool, time entries feeding an invoicing tool, etc.) — you’ll need to rebuild or replace each one.
Who owns what — who’s the admin on each tool, who has billing access, who needs to approve the cancellation later.

The output of Day 1 should be a short list: which projects migrate, which get archived as-is, and which integrations need a replacement. Skipping this step is the single biggest cause of migrations that drag on for months — you end up migrating stale, half-finished work right alongside the stuff that matters.

Day 2: Export and Import Projects

Start with your active projects only — the list from Day 1.

Export first, always. Most PM tools offer a CSV or JSON export of tasks, projects, and comments. Pull this before you do anything else, even if you don’t end up using the raw file — it’s your safety net.
Migrate one project first. Don’t batch-import everything at once. Pick your most active project, recreate its structure manually (columns, priorities, due dates), and use it as a template for the rest. This surfaces structural mismatches early — a custom field or workflow stage that doesn’t map cleanly — while the blast radius is one project, not twelve.
Preserve context, not just tasks. Task titles and due dates import easily. Comment history and file attachments often don’t. Decide upfront whether that history needs to move or whether the old tool stays in read-only access for reference (see Day 5).
Re-assign as you go. Don’t import tasks unassigned and sort it out later — assign owners during the import while you still remember who was doing what.

Day 3: Chat Cutover — Archive, Don’t Delete

Chat migrations fail for a predictable reason: teams try to do a hard cutover on day one, and everyone quietly keeps using the old channel because that’s muscle memory.

Stand up the new chat spaces first, mirroring your most-used channels (general, per-project, per-team).
Announce a specific cutover moment — not “starting sometime this week,” but a specific time. Ambiguity is what causes split usage.
Archive the old channels, don’t delete them. You will need to search old chat history for context weeks later. Archiving keeps it searchable and read-only without competing with the new channels for attention.
Redirect, don’t nag. A pinned message in the old channel pointing to the new one, plus a bot message if your old tool supports it, does more than repeated reminders.

Day 4: Time Tracking and Templates

This is the day teams most often skip, and it’s the reason old habits creep back in a month later.

Set up time tracking categories first — mirror whatever billing or reporting categories you used before, so historical comparisons still make sense.
Build templates for recurring project types. If you run the same kind of engagement repeatedly (a monthly retainer, a standard sprint), build the board/task template once so every new project starts consistent.
Migrate only the current billing period’s time data, if your old tool supported exports. Older time history can usually stay in the old tool for reference rather than being re-entered.
Test the invoicing path end-to-end before you rely on it for a real client bill. Log a test time entry, generate a test invoice, confirm the numbers match what you’d expect.

Day 5: Retire the Old Tools

Keep the old tools in read-only mode for a defined window (2-4 weeks is typical) rather than cancelling immediately. This gives you a safety net for anything you missed in the export.
Set a specific cancellation date on the calendar now, not “once we’re sure.” An open-ended read-only period tends to become permanent, and you end up paying for both the old stack and the new one indefinitely.
Confirm every integration is either migrated or explicitly retired. A dangling Zapier connection still billing you, or a Slack webhook still firing into a channel nobody reads, is the kind of thing that lingers for months unnoticed.
Cancel on the date you set. This is the step that actually realizes the cost savings — everything before it is preparation.

Common Pitfalls

Running two systems too long. The single biggest failure mode. If both the old and new tool are “live” for more than a few weeks, some fraction of the team will default to whichever one they’re more comfortable in, and you’ll end up with fragmented, out-of-sync data in both.

Migrating stale projects. Don’t give a dead project the same migration effort as an active one. If nobody’s touched it in two months, archive it in the old tool and leave it there — don’t spend Day 2 recreating its board.

No single owner for the cutover. Migrations that are “everyone’s responsibility” become nobody’s. Assign one person to drive the week, make the day-by-day calls, and be the one who actually cancels the old subscriptions on Day 5.

Skipping the test invoice. Time tracking and invoicing bugs are invisible until they touch a real client bill. Test the whole path with fake data before the first real one goes out.

A week is enough time to do this properly if you sequence it — audit before you migrate, one project before all of them, archive before delete, and a fixed date before you actually cancel anything. The tool you’re moving to matters less than doing these five things in order.
