how shall I upgrade the compltete page from 4.0 to 4.4. In the description it says:
Remove all files from the previous version except JSON files in the 'App_Data' directory such as dataSettings.json (Settings.txt in oldest versions), plugins.json (InstalledPlugins.txt in oldest versions), appsettings.json, move them to the safe place.
But what about style sheets, themes, changes in the source code in various projects through the whole solution ?
We did a lot of changes in the source code how to migrate them ? Do we have to do all of this manually ?
What about all the plugins and customizations there?
Any ideas and hints would be appreciated. THX
