Upgrade from 3.4.11 - Any tips or gotchas?

[mterry63]

Michael,

I'm needing to upgrade from version 3.4.11 to the current, I'd like to take advantage of the device history/SQLite/InfluxDB featues of the newer version. Any issues I need to consider to jump so far ahead?

The general case is to maintain backward compatibility so I expect the database to be compatible. It is a big version jump and I may have forgotten something, but there is nothing to do except jump in and test the waters. A backup of HS folders will cover mcsMQTT as well.
