We are attempting to migrate Exchange2003 on Windows Sever 2003 Standard to Exchange2010 on Windows server 2008 R2;
1) Whilst attempting to DCPROMO the DC that is 'Front End Exchange'. When they try this it says it says "cannot perform the action due to the server operating as an internal CA server". How can we remove the internal CA role from the server? Also, how do we transfer the CA to a new server as there are certificates in place?
2) We still have some legacy references to the Exchange 2003 environment after the uninstall on both servers, now in the case of the front end, this didn't work cleanly and we had to remove manually. So we are looking for some advice on what the best cause of action would be to take in order to clean up the environment?
3) We also need to either edit and upgrade the Address Lists and also the Email Address Policies on the 2010 servers as they are currently configured in a legacy 2003 setup.
4) Finally, We also have issues with Distribution groups not functioning in the way they used to under the 2003 environment, i.e. some users who managed the various distribution groups no longer have this privilege. When we check properties of the distribution group, all looks fine?
Any advice is greatly appreciated, Thank you!
