backward compatibility for g9 with g7
welcome @justanotheruser
is this a hosted service or on prem? Are you trying to do in place upgrades or in a test/qa environment?
is the QA environment identical to the others? also how many dashboards are we talking about and how many datasources for these?
what is the upgrade method you are using?
I would be tempted to try this
- back up prod
- restore to qa
- do the upgrade
- backup qa
- restore to canary
manual but might prevent the headaches? or is that too tedious
I would look at release notes of v9 for disableEnvelopeEncryption
