Nimbostratusmigrate from serie I to R. Cluster LTM-GTM
NimbostratusThanks a lot for your response. Ill go to the second one (BINGBANG). iseries and tenant(rseries) will be the same 17.5.1.3.
My idea is to put the new R Series node in standby, remove the cables from the standby iSeries node, and connect them to the new R Series node instead.
My question is whether the synchronization from the active node (iSeries) to the passive node (R Series) would work correctly. Would the configuration synchronize (LTM/GTM) properly, or could it fail because the hardware is different (tenant)?
CirrostratusAs long as the devices in the cluster run an identical TMOS version, the sync should work.
Additionally, license and resource provisioning should align.
The following KB provides a detailed explanation.

In order to add the new serie R device to the GTM existing cluster. Its only necesary add this command in the new member "gtm_add IP_EXISTING_MEMBER CLUSTER".
What about bigip_add? is this also need it?

My idea is to configure the new R-Series devices as a cluster and, during the maintenance window, remove the old iSeries standby unit and connect the R-Series interfaces while keeping them in standby mode.
I would then verify that the entire LTM configuration is working correctly (all Virtual Servers showing green status) and subsequently run the big_add and gtm_add commands on the new node.
My question is whether an R-Series device that belongs to a different cluster can synchronize with a different HA group. I'm not sure if that's supported. I hope you understand what I mean.
