Replacing LTMs in GTM Server List
I am currently working towards replacing two pairs of HA LTMs. Each pair is configured in GTM (separate appliances) as one Server with two Devices. The GTM configuration can be represented as
DC1 ->ServerDC1->LTMDC1-1 + LTMDC1-2
DC2->ServerDC2->LMTDC2-1 + LTMDC2-2
To prevent losing virtual server and pool objects, I believe the best way forward is to replace the LTMs one-by-one in the GTM Server configuration:
1) shutdown LTMDC1-1
2) delete device LTMDC1-1 from server Server DC1
3) assign OLD LTMDC1-1 self-IPs to NEW LTMDC1-1
4) add NEW LTMDC1-1 as a device to ServerDC1
5) big3d_install & bigip_add NEW LTMDC1-1
6) Rinse and repeat: LTMDC1-2, LTMDC2-1, LTMDC2-2
Am I on the right track here?
