GTM sync

Here is what I would do based on the F5 implementation guide:

 

1. Add the new GTM under "servers" in one of the GTM's. This will make sure that keys are exchanged *** MAKE SURE SYNC IS DISABLED ON THE NEW BOX **

 

1. Remove devices from sync group first

 

2. Make sure they are independent and you don't see any sync session going good. Might be good to run "tail -f /var/log/gtm" in the background for messages

 

3. Change sync group on one of the running device say "A" (with current config) to "new name"

 

4. Run "gtm_add A" on the other devices (excluding new GTM). This will fetch the config from "A" including sync group. Check syslogs etc. to make sure that all device are in the sync group. Create a test server and make sure that it is reflecting on other GTM's too [optional but a simple check]

 

5. Run "gtm_add A" on the new GTM which will also fetch the config and I hope will get the sync conf too.

 

 

** From my experience I had seen that if you break the sync group and add the devices back to the same group, it doesnt work. Somehow it doesnt like the same name. I ended up configuring new sync group. I didnt get satisfactory answer from support as why it did not work :-) **

 

 

ALL THE BEST! Make sure you backup the config before the activity and dont enable sync settings on the new GTM without "gtm_add" first
