# Introduction
This migration has been introduced in 0.54 we should determine how we
wanna handle retro-compatibility with this, might not wanna merge this
one latest main 🤔 but only a new 0.54 patch
related to
https://github.com/twentyhq/twenty/issues/12651#issuecomment-2988164122
## Concerns
If a workspace fails this migration that's not a good sign, the metadata
schema should be completely empty since 0.54 `metadata` merge into
`core` migration.
Please review you existing entries in the schema and verify they exists
in the dest `core` one
