pls advise the possibility of import the old datas of only on particular period from desktop version (from old back up) to current cloud version.
Have you tried it? You should be able to import old data. If not, you can email your backup file to
email@example.com to see what’s the issue.
To be clear, you will not be able to import just data from a specific time period. Only entire business data files can be backed up, restored, or imported.
