Upgrading BIG IP LTM appliances

I just want to post an update to my progress for others researching this topic.

 

 

I have successfully moved the config to new hardware, in order to do this I did the following.

 

I had a standalone 1600 and a HA pair of 3600's. I broke the HA pair and deleted the necessary groups, trusts and self IPs.

 

I then created a HA pair "sync-failover" between the 1600 and 1, 3600. They joined perfectly and I then went to the Active unit (1600) and did Config Sync TO Group. Waited about 2 minutes and the sync status came back and said "In Sync".

 

 

I thought it was going to be much more difficult than this but it was really was easy.

 

I disabled the 1.1 internal interface on my new 3600 and broke the HA pair by deleting the same groups, trusts and IPs. I will now schedule a hard cutover and simply disable the interface on the 1600 and enable it on the 3600 and recreate the HA pair on with the standby 3600.

 

 

I thought about leaving the 1600 and 3600 in HA mode and then forcing the 1600 to standby and keeping all the stateful information with no outage but choose to do the full cutover instead.
