AD Migration

Hi,

We want to migrate users from domain A to domain B. We want to update user from domain A to domain B such that they retain their personal views and all the related data.

If we migrate AD that means the users will migrate from old domain to new domain. How to migrate the users in the CRM from the old domain to new domain?

Both the Domain fall under different Forest but they share two way trust between them.

Thanks

Vasu
