How to do a version upgrade and keep the existings projects

[haluwong]

Hi All, I'm running v0.84.2 and it's a bit old and i would like to ask the guideline to upgrade to the latest release v0.107.1?
I tried to delete all the existing unstract container and keep the volume.
Then, download the current latest release: v0.107.1, decompress and ./run-platform.sh
The login screen can be shown but show error after login

Attached with the container's log for unstract-db
_unstract-db_logs.txt

unstract_db has tables but unstract is empty

Please kindly advise how to do the version upgrade and keep the existing projects/workflow data.
Thanks,
Halu

Hello @haluwong

Since v0.93.0 there has been some changes in how we store data. Can you attempt to follow this migration guide to move existing data into the new structure and make it usable for the latest versions?

Since it involves significant changes in the schema structure we didn't want to automate this directly for the user. Please try it out and let us know if you face any issues
