I currently have 3 x 3600's with the following configuration:
1 x Master (serves as a backup to the locals)
2 x Local
They are all running 6.4.3.5.
The 3600's are being replaced with a pair of 7210's in a master/standby setup. From what I read, it seemed that performing a flash backup of the 3600 master and restoring on the 7210 would migrate all the configuration. However, after successfully restoring the flashbackup.tar.gz, I found that many parts of the configuration were missing. Both the 3600 and 7210 were both running the same version (6.4.3.5). I am now thinking the best way to migrate the master is to do the following:
1. Add the 7210 as a standby and let the system sync the config from the 3600 master to the 7210.
2. Make the 7210 the new master and remove the old 3600 master.
3. Add the 2nd 7210 as the new standby.
4. Change priority to migrate AP's from 3600 locals to new 7210 master/standby.
Does this migration plan seem correct, or is there a better way? Thanks.
