GTM Synchronization Group Modify Self-IP Resynchronization

I have four GTMs which are in a sync group, due to relocation of the equipment to the server room I need to change the self-ip , please advise me how to do the change without changing the configuration of the sync group.
Thank you very much.

  • Hi Forrest-Z,

    Wich is the specific self-ip for that you have to change?

    Listener?

    HA selfip

    The DNSs are in a standalone state with a iQuery sync? Please provide more info for a better understanding.

      I know I need to change the listener and self IP, what I'm asking is to add the new self IP to the server -devices address list to automatically modify the iquery synchronization. Can I add the address for iquery synchronization and then delete the original address. Without changing credentials and without re-executing the gtm_add

      I tested the GTM synchronization by deleting the self on the device and then adding a new self ip. I also changed the corresponding device ip on other devices in the synchronization group, and the query connection will be established automatically, and the GTM synchronization function is normal.

  • Hi,

    I believe if this IP that will be changed is a self IP used to define the F5 GTM as a server object, you will need to add this GTM device as a server again.

    Therefore, I recommend disabling the GTM sync group on the GTM that will be relocated, modifying its IP, and establishing the required connection between the old GTM nodes and this F5 GTM.

    Once you've completed these steps, you can proceed with the BigIP script and finally run the GTM add command on the relocated device.

    Don't forget to remove the node from the existing setup that was using the old self IP and remove its certificate.

    Thanks,

      and first of all, remove the current self ip addresses of the intended gtm from DNS IN NS entries

        Since the equipment has been running for 15 years, I don't want to make major changes. Is it possible to not renew the certificate? Or is it possible to change the self-ip?
