Slack Migration in London
Moving London organisations into Slack or across to another platform. Message history is the question that decides the shape of the project — what you can export depends on your plan and on whether private conversations are included, and organisations frequently discover the limits at the point they are trying to leave.
Why this comes up
The problem
The messaging platform is changing, and years of conversations contain decisions and context that exist nowhere else.
What you get
What we deliver
- Export scope established, since plan and privacy settings determine what is available
- A decision on what history genuinely needs to move rather than be archived
- Channel structure redesigned rather than replicated from the previous platform
- Integrations and apps reinstalled deliberately, keeping only what is used
- Files handled explicitly, as these are frequently separate from message exports
- Retention and legal hold obligations checked before anything is deleted

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Slack Migration in London — common questions
- Can we export everything?
- It depends on your plan and settings. Public channel history is generally exportable; private channels and direct messages require particular plan levels and, in some cases, an approval process. Establishing what is available before promising a full migration avoids an awkward reversal.
- How much history should move?
- Less than people expect to want. Conversations older than a few months are rarely consulted, and importing years of chat into a new platform produces clutter rather than value. Archiving the export somewhere retrievable satisfies most of the underlying anxiety.
- Should we recreate our channels?
- No. Channel lists grow through years of ad hoc creation, and most are dormant. A migration is the one opportunity to start with a deliberate structure, and replicating hundreds of channels imports the problem you might otherwise have fixed.
- Are there retention obligations?
- Possibly. Messages can be business records, subject to retention requirements or legal hold in a dispute, and deleting a workspace during a migration is not neutral. Checking whether any hold applies before decommissioning is a short conversation worth having.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
