I have a question. Is it possible to perform a version downgrade in Dataiku?
For example from version 11.3.1 to 11.2? Or from another version, has anyone done it?
Operating system used: Linux Red Hat 8.7
Because I updated the test environment and in case it generates an error in version 11.3, I wanted to know if I could downgrade it to the previous version 11.2 without the need to apply a restore.
If I backup the datadir I could run the following steps on the same machine:
Upgrade with 11.2 software. step to 'reattach'
Hi @AliciaCGuti2906 ,
I would first suggest you raise a support ticket https://doc.dataiku.com/dss/latest/troubleshooting/obtaining-support.html attach the instance diagnostics and job if a particular job is affected and we can advise further.
The restore steps would be what you describe
restore the datadir and possible external runtime database ( if you use external one)
re-run the 11.x installer with -u flag and then perform all post upgrade tasks again.
