Problem while deploying Package to Environment

0
Hello to all! I would like to ask some help please. My app is currently in Mendix version 10.12.16. Yesterday afternoon I uploaded a test package to the environment in version 10.24.11. Last night I uploaded a package to the current ACCP version (10.12.16) and it got stuck at Runtime.     Unfortunately our ACCP environment is down now. Have anyone faced a similar issue?  Thank you so much!   This is the log that I got:   2025-11-07 10:24:19.370 INFO - Core: Mendix Runtime is now shut down.[root@accp ~]# kubectl logs digoffic-master-dd8b77856-ng5sw -c mendix -n accp-se-mendix-nmsp | grep err2025-11-07 10:24:19.302 ERROR - M2EE: An error occurred while initializing the Runtime: Unsupported pre-analysis migration version: 4.4.0.

Hi Danilo,

You deployed a 10.24.11 package somewhere that pointed to (or migrated) the same database ACCP uses.10.24 wrote newer migration metadata (“pre-analysis migrations”) into the DB.When you later started 10.12.16 on that DB, it refused to boot because Mendix doesn’t support DB downgrades. Solution:

  • Restore the database to a timestamp before the 10.24 deployment

    • Managed DB: do a point-in-time restore or restore snapshot.

    • Self-hosted PG: restore from backup dump.

  • Restore the file storage (object store / volume) to the same point in time.

  • Start the app again with 10.12.16 runtime & package.

  • Verify it boots and data looks consistent.

Just to make sure, you only have a accp and a production environment? Because indeed you can not downgrade your database. You already started an 10.24.11 and then tried to start 10.12.16. You need to restore the database first to the version before the 10.24.11 and then you can upload the 10.12.16 version.

Ronald
