Upgrade gateway sql tag related classes from 7.9 to v8.1

Hi,

We have few custom modules in Ignition 7.9. We are working on migrating those to Ignition 8.1. The below APIs seems to be missing in Ignition8.1
Could you please help us with guiding how we can migrate these to 8.1.

Package
com.inductiveautomation.ignition.gateway.sqltags.model.ExecutableScanClass
com.inductiveautomation.ignition.gateway.sqltags.model.ScanclassEvent
com.inductiveautomation.ignition.gateway.sqltags.model.ScanclassListener
com.inductiveautomation.ignition.gateway.sqltags.providers.RedundantProviderWrapper
com.inductiveautomation.ignition.gateway.sqltags.scanclasses.SimpleExecutableScanClass
com.inductiveautomation.logging.SQLiteAppender Not present in docs
com.inductiveautomation.ignition.gateway.logging.GatewayLoggingManagerImpl Not present in docs

v8.1 doesn't have scan classes any more. All of that functionality has been replaced with tag groups. You'll have to rewrite those parts of your modules.

v8.1 also replaced its logging infrastructure. You'll need to re-implement any related customizations in the logback framework.
