Hey @peterg , Do you have a draft of those steps you followed to upgrade by any chance? In my case this is the sequence I followed to upgrade with a few errors that do not give me the assurance to rely on the integrity of the data after upgrade.
First I installed Ubuntu 22.04 so that I can have the required python, pip etc. version already installed on the OS. Then I installed ERPNext version 13.36 I believe and restore data from my version 13.2 successfully. After the restore was done I followed this doc to upgrade from version 13 to version 14:
After the upgrade I found some errors on the app in different doctypes itself and also some errors related to table missing on the terminal while upgrading.
