Is LMS 2.6 or later going to support Software Image Import from the FWSM, or is this the role CSM is supposed to fill? Can CSM co-exist on the same box as LMS 2.6?
No, image import from the FWSM is not supported in LMS 2.6 or 3.0. I have not heard of any plans to support this. Since CSM also relies on RME for this kind of functionality, I do not see CSM providing this functionality either.
No, LMS and CSM cannot coexist on the same server.
