**RESOLVED** MMAP to wiredTiger Migration | MongoDB 5.X and RocketChat 4.X Upgrade

Description

I have been trying to upgrade my test RC server to the latest so I can do the same in our production server. (As in MongoDB 5.x and RocketChat 4.X.) However, I keep ending up with this same error.

The migration from MMAP to wiredTiger seems to be a success by checking the logs and following this(GitHub - RocketChat/docker-mmap-to-wiredtiger-migration), but the rocketchat log says something else.

Hi!

Looks like a Rocket.Chat version mismatch to me.

can you make sure you are running the now migrated mongo db with the same Rocket.Chat version from the nmap version?

migration 240 is the last one, according to here:

Thanks @dudanogueira! You’re the champ.

I went back to my docker-compose.yml and updated the line for rocketchat image.

“image: rocketchat/rocket.chat:latest” >> “image: rocketchat/rocket.chat:4.0.1”
