Ghost 11 is quite an old version, and even the latest available release, 11.5.1.2266, is several years old and only the 2266 build fully supports Windows 7, which is the equivalent code family to 2008 R2.
I cannot suggest anything other than to give it a try in your environment and see how it works. Please also bear in mind that V11 came with DOS compatibility only, so unless you have your own WinPE implementation set up, you are likely to run into increasing difficulties handling modern hardware which DOS does not support (eg SATA).
