How to downgrade FMS and deploy a backup to the current DB

hello community, hello Todd,

On July 17, 2025, we compressed our database in the production environment, then migrated the development environment database to the production environment, and then upgraded Filemaker Server to version 22.0.1.66. Since then, we have been experiencing crashes of the fmserverd process. But only in the production environment, presumably only under load.

My plan now is to downgrade to FMS 21.1.4.400 and migrate the backup from before the compression to the current DB.

The goal is to fill the structure of the old database before the compression to FMS 21.1.4.400 with the data from the current DB.

Will that work?

We recovered the current DB. Only one invalid Relationship to a deleted TO was found. The recovery.log stated that the invalid relationship had been deleted, but it was still present in the restored database. However, I assume that the database is not the problem.

I will start in 3 hours.

Thanks in advance!

Hello,

I think you are asking if you can import data from the current file into a backup. If so then the answer is yes, that will work fine.

But if you did a recover and it found corruption then that corruption is likely in the backup also. But it may be the best you can do.

Hope that helps

Thanks

Todd
