Could you please send some more details? Database migrations can fail for a number of reasons. Also, would you be able to use English? Only a few people in the community understand Spanish.

It is already migrated but now nothing works

It was working fine, I got that message and it stopped working.

Hi,

We're reaching out to inform you that your legacy databases have been stopped:

Postgres
Please migrate them to our newest database version by clicking the links above and following the instructions. You have until February 23rd, 2024 to migrate. If you do not migrate by that time, your databases above will deleted.

We will archive the data of active databases before this deprecation for up to 6 months from February 23rd, 2024. If your database is locked due to a lack of recent payment and/or insufficient dollar credits for compute & storage resources, your data will be permanently deleted.

If you no longer need the legacy databases above, no action is required. If you have migrated your databases manually without using our one-click migration button, you can safely ignore this email.

For further information, refer to our Migration Guide. If you need help with the migration, reach out to us over Discord, Community Forum, or by replying to this email (support@railway.app) for Pro Plan users.

Best,
The Railway Team
