**DO NOT** migrate all the information to the new one. Use the old and new one in parallel. New information will go to the new app. Related old information (unfinished project) will go to the old app. Reduce the time of using the old app. When we need information. Use the one in the new app. If we can't find it, copy it from the old app to the new one and marked migrated to that information in old app -> from now on, only use | update the information in the new one.
