I will migrate self hosted n8n and fix breaking changes


About this gig
Did your n8n workflows fail after the n8n 3.0 update, or are you afraid to click upgrade?
n8n 3.0 removed the Function, Function Item, Item Lists, Cron and Read Binary File nodes, made Docker the only supported self-hosted install and changed several defaults. Workflows that use a removed node simply fail. I handle n8n breaking changes end to end so your automations keep running.
HOW I WORK
1. Run your built-in Migration Report and list every affected workflow
2. Back up your database and encryption key before anything changes
3. Replace removed nodes with their official 3.0 equivalents (n8n refactoring, not patching)
4. Test on a staging copy, then upgrade production in a planned window
5. Hand over a written change log and a rollback plan
WHAT YOU GET
Deprecated Function nodes rebuilt as Code nodes
Docker VPS check, or migration from npm
Env variables pinned where 3.0 changed defaults
Nothing goes live without your approval
You keep full ownership of your server, accounts and workflows.
Message me your n8n version (Settings > About) and how you host it.

FAQ
Can you convert my old Function node code?
Yes. Removed Function and Function Item nodes are rewritten as Code nodes, then tested against your real data so the output matches the old workflow.
How is my data protected?
I work on your own server through a temporary user you remove after delivery. I never ask for passwords in chat, and your credentials never leave your instance.
Will my n8n server crash or lose data during the upgrade?
I back up your database and encryption key first, test everything on a staging copy, and keep a rollback plan ready. Production is only touched in a time window you approve.
