Merging two different LTMs in a HA Pair - Q's

I wonder if there can be some problems while adding the second device to the pair, that already have some config fragments identical to the first device (for example hostname, or probabbly many others)

 

Any ideas?? i think you have to change hostname and unit id of 1600 unit.

 

 

What will happen if both devices have the same license... I mean physically exactly the SAME one. you cannot just move license (base registration key) from 1600 to borrowed 3600 unit. the license is tied to unit serial number. you should contact F5 guys to get temporary license for the 3600 unit.
