No, right now there is no way for CloudManager to be aware of domain name changes.
However you can export and import some of the information stored in CloudManger.
A lot of your information in CloudManager is already influence by Google, however not all, so several steps are required in order to have a copy of your own profile data to be re-imported once CloudManager is re-installed on the new domain name.
Export user profile data
Firstly you'll want to go to your Root Organisation and then from the 3-dotted menu in the top right select export
You'll be presented with a menu item asking what format you want your file to be in, and if you want to export all the child OUs, be sure to enable this
Make sure you tick to select Export the profiles of the child OUs
Once you've enabled that, select the format you want and click the export button.
Export external contacts
After this is done go to the External Contacts OU (if you have any) and export those too using the same method described above.
Smart Groups/Contacts will be lost, they'll just be manual items in G Suite, also any custom roles or OU rules you have in place will also be lost.
Exporting email signatures
Go to Email Signatures, click on "Tools" and then "Source Code" and then copy all the text shown into a text file that can be copied from later back into CloudManager.
Multiple Email Signatures
Make sure that you copy/export all the signatures you have across your OUs - e.g. and sub OUs that have their own Explicit email signature.
Export source code option:
HTML source code
You can now use the data from the 3 steps above as an import into your new domain and new install of CloudManager
- User profile data
- External contacts data
- Email signatures
