Internally sql server uses SID of NT users to link them
with sql logins. I don't know if NT will preserve SIDs
when users are migrated to another domain. If it does then
users can login with Domain2\user1 and still have same
permissions in sql server based on their SID stored in
sysxlogins table, though their username will be displayed
as Domain1\user1. You can update sysxlogins table and
change users display name.

If users are assigned new SID by NT then I am afraid you
have to add them again and assign permisstions.

change the database permissions to reflect the new domain
names. Example Domain1\user1 is migrated to Domain2. user1
is now Domain2\user1. In SQL, the user is still displayed
as Domain1\User. Any idea. Thanks in advance.

    ... The option of creating a login with a specified SID is provided for allowing SQL logins to be moved from one server instance to another - this means you already have access to a SID from the syslogins catalog; you don't need to generate one yourself. ... It is true that SQL Login SIDs are actually GUIDs, but the SID you selected below is a SID, not a GUID. ...
