got one question about downgrade and recovery after failed update in HA cluster (A-P).
When update failed and need to downgrade and upload configuration once again the best way for this is to:
1. disconnect slave from HA,
2. downgrade firmware and config to master
3. reconnect HA
4. wait for slave to sync?
But what when both units failed with updates and need to downgrade also Slave?
Only difference is that need also to downgrade slave?
In this scenario should I also upload config on slave or only on master and after connecting to HA wait for sync?
When making configuration backup notice only got config from Master, is there any scenario I should have config file from Slave?
