I am currently working for a small manufacturing company. The current setup is a 2 Server system, with one Windows 2000 Server SBS edition machine (original server), and one Windows 2003 Server Standard Edition (Added about 3 years ago to run a new ERP system). We have about 20 workstations.
The Win2k server machine is about 9 years old and I would like to see it retired in the near future. I have moved our email to the cloud to lighten the load on it, however it is still the PDC, handling AD/DHCP/DNS as well as some simple file sharing and a shared Fax. The Server 2k3 machine is barely being taxed and could probably easily handle the extra work load.
Not having much (any) experience with windows server migrations and upgrades, I was hoping to get some input as to what options I might have and what would be the easiest course of action. I have been given the OK from management to purchase another server if needed, however with all of the options out there from 2008 Standard to 2011 SBS, I am not sure what would be the best solution and make for an easy transition. If it was a newer version of SBS we were upgrading from I understand there are migration tools available, would these possibly still work with a legacy version? Is going from SBS to a standard version even an option?
Any help/suggestions would be greatly appreciated. I understand there is probably no right or wrong answer but I will do my best to assign credit fairly.
