I think on recent XOA we even switched to systemd-timesyncd. Pinging @thomas-dkmt so he can update the doc to fix it (only the new doc directly! oh and you can ask @julien-f for details if needed, thanks!).

Not looking to revive this topic but wanted to post this documentation I found in case anyone else searching for answers stumbles here like I did. There are too links on this site that address some limitations that are not readily documented in the standard migration documentation. https://help.vates.tech/kb/en-us/37-import-export-migration
