I am migrating from an sbs 2003 box to new Essentials 2012 R2. I find the documentation not as clear as it is in migrations to previous versions. I understand there is no 'migration install' mode but it still seems that the new server becomes a dc on the existing sbs 2003 domain. My assumption then is/was that on the client side, PCs and Users, it would all migrate over since the users/PCs are still in the same domain. But I read in the instructions that you have to uninstall the sbs 2003 connect software and then connect the PCs to the new server. My concern is that after that process, the user profiles on the client PC (they are not roaming) won't work and and new blank ones will be created since the PC is now connected to the new server. Is this so?
Will profiles created on a machine joined to the domain before migration, still be used on a PC which the connector program to 2012 essentials was run?
I don't have a lab or any extra machines to experiment with...
