We have a mixed use of 7.4.121 and 8.0.100 on wism2s here. After HA mode on 7.4.110 failing and then the 7.6 update debacle we are being very careful indeed. While we've been running a HA pair on 8.0 for a while with ~180 APs, we recently loaded it up to 640 to load test. Everything seems to be ok so far so we're planning on upgrading the rest of them in late January (after the examination period). Hopefully 8.0MR1 will be released in the meantime and won't introduce any terrible bugs like the various 7.6 MR releases did.
