Changing the tools an agency runs on is disruptive. Projects are live, clients are waiting and the team has habits built around the current setup. That is why many agencies stay with tools that no longer fit long after they have decided to leave.
A migration does not have to be a big-bang weekend. Planned well, it can be a series of small, reversible steps. This guide sets out a plan that works whether you are leaving ClickUp, Zoho, Trello, a mix of them or spreadsheets. It is written to be honest about the work involved.
The useful idea
Move what the team needs to work tomorrow, archive the rest where it can be found, and set a date when the old system becomes read only. A migration without an end date becomes two systems.
Write down why you are moving
Start with the problems you want to solve, in the team’s words. ‘We retype client details between three tools’ or ‘nobody can see a client’s invoices from their project’ are useful. ‘We need something better’ is not.
Keep the list. It becomes the test for the new tool during the trial and for the migration afterwards. If the move does not solve the problems on the list, it was not worth the disruption.
Take an inventory of what you have
List every tool in use and what lives in each: clients, contacts, deals, projects, tasks, documents, time entries, invoices, files and automations. Note who owns each and how much of it is current.
Be specific about automations and integrations. A rule that assigns new tasks or sends a reminder is easy to forget and painful to lose. Write down what each one does so it can be rebuilt or deliberately retired.
| Data | Usual decision |
|---|---|
| Active clients and contacts | Move |
| Open deals and proposals | Move |
| Live projects and open tasks | Move, with current status |
| Completed projects | Archive, keep a link or export |
| Closed tasks and old comments | Archive in the old tool or an export |
| Time entries and invoices | Move the current period; archive history with finance |
| Templates and automations | Rebuild deliberately, not copy |
Decide what to move and what to archive
The instinct is to move everything. It is usually a mistake. Old tasks, abandoned projects and years of comments rarely help anyone and slow the migration down. Move what the team needs to work tomorrow and what clients may ask about soon.
Archive the rest somewhere it can be found: an export stored with clear naming, or the old tool kept read only for a period. Agree with finance what must be kept for accounting and how.
Run both systems for a short, fixed period
Choose a pilot: one team or a few clients that start in the new tool while others stay in the old one. Learn from the pilot before moving everyone. It will reveal fields you forgot, habits that need a new home and training gaps.
Set a cutover date at the start and keep it visible. Running two systems is tiring and confusing. A few weeks is usually long enough to learn; months of parallel running tends to mean neither system is trusted.
Train around real work
Train people on the tasks they do every day, using their own clients and projects, not a generic tour. An account manager needs to find a client’s history; a designer needs to see their week; finance needs to raise an invoice.
Name a go-to person in each team for the first few weeks. Questions get answered quickly and patterns of confusion become visible, so you can fix the setup rather than repeat the explanation.
Cut over and close the old system
On the cutover date, move the remaining live work, make the old system read only and tell clients about any change that affects them, such as a new portal link. Remove the old tool from bookmarks and onboarding documents.
Review after a month against the list of reasons you wrote at the start. Fix what is still causing friction and retire the old subscription once the archive is confirmed.
- Live work moved and checked by its owner.
- Old system read only, with an archive link.
- Automations rebuilt or deliberately retired.
- Clients told about anything that affects them.
- Old subscription cancelled after the archive is confirmed.
Clean the data before you move it
Every system collects duplicates, outdated contacts and half-finished records. Moving them carries the mess into a tool the team hoped would be cleaner. Before importing, merge duplicate clients, remove contacts who have left and close projects that ended long ago.
Agree naming conventions for the new tool at the same time: how clients, projects and stages are named. A short page of conventions saves months of inconsistent records.
- Merge duplicate clients and contacts.
- Close or archive finished projects.
- Agree names for stages, statuses and labels.
- Check each live project’s owner is still correct.
Plan for what can go wrong
Common problems are predictable: a field that did not import, an integration nobody listed, a client link that changed, a teammate who keeps working in the old tool. List these risks before the pilot and decide how you will notice each one.
Keep the migration reversible for as long as possible. Until the cutover date, the old system should still work. After it, the archive should make every old record findable, so nobody feels they have lost something important.
If you are moving to Tamaam
Tamaam’s Agency plan includes a guided move from Zoho, ClickUp or Trello, and imports from those tools or a spreadsheet are part of setting up a workspace. It is in early access, so confirm what your import needs with the team before you set a cutover date.
Migration and cutover plan
Keep this as the single plan for the move.
SOFTWARE MIGRATION PLAN Reasons for moving: [problems in the team’s words] Tools being replaced: [tool / what lives there / owner] Move: [data type / from / owner / done] Archive: [data type / where / how to find it] Automations: [what it does / rebuild or retire] Pilot: [team or clients / start date] Cutover date: [date] Training: [role / tasks covered / go-to person] Client communication: [what changes / message sent on] Old system read only from: [date] Subscription cancelled on: [date] One-month review: [what improved / what still hurts]
Bring the context into your workspace.
