looks like this is more of a Creative Cloud query.
Let me move this thread to Adobe Creative Cloud forum so we can get relevant solution by experts.
Thanks Preran and Ankush. So on behalf of Adobe Muse can you guarantee that I can update without any problems?
Even if you update to the latest version of Muse (CC 2018) it has a facility to save the backup copy automatically in previous version. Or you can also make a manual backup file for other versions.
later if seeing any problem you can come back to the previous version of Muse.
