I just migrated from Data Point 6.2.0.23226 to 6.3.0.28375, but the highlighting styles and auto-replace settings did not migrate correctly. I am using a dark mode theme and after looking at the app and data directories (to manually copy over the appropriate files) it appears that there are now separate files for both regular and dark mode. This is a great enhancement but the issue is that the migrated settings are only applying to the normal mode files and not the dark mode files.
My suggestion is that on migration, if there is no dark mode file in the source, then the "normal" mode files should be copied over and duplicated for dark mode as well.
EDIT: This is worse: Auto-replace settings don't appear to work with dark mode? I have a ton of auto-replaces for SQL Server. In 6.3 data directory>Templates>CodeTemplates, there is file CodeTemplate.SQL.SqlServer.merge.xml that contains my migrated auto-replace rules. But like the highlighting styles issue above, these are not being referenced in dark mode. So like I did with highlighting styles, I copied the file and renamed it to CodeTemplate.SQL.SqlServerDarkMode.merge.xml but these are not being picked up in the app. When navigating to the setting in the UI, there is also no SQLServerDarkMode in the language drop down , so I can't manually recreated them via the GUI either.
So frustrating. because the black text in dark mode issues that have been around for years seem to be finally fixed in this version but now a major productivity feature is broken. 
I've submitted case #02492492
