I have a Cisco SFR in the form of an FMC running version 220.127.116.11. It is supporting firepowers running version 18.104.22.168. The FMC is just an FMC; it is not an FMCv300. For some reason, I was under the impression version 6.7 was as high a version the FMC can support before having to upgrade to the Cisco NextGen series, so I need to find out if this is true. Recently, we found a bug causing cosmetic LDAP errors and it was recommended we upgrade to version 7.2. Is this possible? If so, can someone forward me the link for the FMC and firepowers software? Also, because our firepowers are running version 22.214.171.124, will version 7.2 support them or do they have to be upgraded to another version as well?
