here follows the current scenario:
Our farm is running MS SharePoint Server 2007 SP2.
Our corporate, is migrating all accounts from DomainA to DomainB. For example, user DomainA\XXX will be migrated to DomainB\XXX.
DomainA and DominB are with trusts between them.
I would like to know the possible consequences of this account migration (I think catastrophic) and whether there are tools or best practices able to support this use case.
About migration on users I only know that sid user history will be preserved. But I'm not sure that SharePoint will still recognize the correct user after migration has been performed.
