Migration from Active Directory 2012 to Active Directory 2019

Hello,

We have one identity manager version 8.1.3. Years ago, under version 7.1.1 we have created a synchronisation projects with an  Active Directory 2012. We are still using it.

After that, we have installed new Active Directory with version 2019. This AD is synchronised with the 2012 AD.

Now we want to swap One Identity Manager synchronisation project  to   2019 AD.

IS there any guide  on how to achieve this ? Should we re create another synchronisation project with the 2019 AD ?

Or , as the 2019 AD and 2012 AD are sync , should we only change the  parameters and url in the CP_ADServer in the synchronisation Editor to the url of 2019 AD?

Thank you 

Best regards,
