# Team EnderChests migration

## Do i need to migrate my team EnderChests?

You will need to perform the migration **ONLY** if you are currently on 1.21.4 or below and you want to upgrade your server to 1.21.5+.

### Steps

1. Stop the server, then backup your database (if you are using H2, or SQLITE it's the file that is called UltimateTeamsData in the plugin's folder)
2. update UltimateTeams to latest version from Modrinth \
   \
   (if you're using cross-server update on all backend servers, but stop all except for the one you will use for the migration)
3. start the 1.21.4 server and use **/ta echest migrate start** 
4. wait for the migration to finish.\
   \
   if you get any error like "material cannot be null" it means that probably that specific enderchest might be corrupted. you can join the Discord server for help.
5. now you can update the server to 1.21.5+

## What if i already updated because i didn't know?

In that case, you can just create a new 1.21.4 server and use that to perform the migration.

but not that if a player opened an enderchest, and you did not migrate first, that specific enderchest might get corrupted.
