GTM Sync

Hi All,

 

We are having two GTM devices, One is in Prod and other in DR. Both are in Sync Group. Also just for info having two LTM(Active+Standby) in Prod and one LTM in DR.

I am planning for upgrade all devices to 14.x version from 11.x

 

Query:-1

I could see my Production GTM is having two listeners(eg:- 10.10.10.1, 10.10.10.2) and DR GTM having one listener(10.10.10.1)

I just want to understand, if i will make offline Production GTM for upgrade, I understood that DR GTM will handle traffic of listener 10.10.10.1, but what will happen for other listener 10.10.10.2 traffic.

 

Query:-2

I am planning to upgrade DR GTM first. After upgrading DR GTM box, big3d version will also get upgraded. Then do i need to upgrade big3d version on all five F5 devices mentioned above which are in iquery or no need to upgrade on LTM?

I am following below article:-

    ==> Will personally not recommend you to directly Jump version from 11.x to 14.x. Lot of feature has changed to GTM. It may not allow you to reload the configuration. Check with F5 Support Engineer before taking any steps.

     

    Query:-1 ==> Take out DNS statics for listeners 10.10.10.2, If require then configure listeners to other GTM and then upgrade. One more solution is to break SYNC group[Just change the name of SYNC Group] and upgrade based on the requirement. You will face DNS[listeners - 10.10.10.2] issue only during GTM reboot time.

     

    Query:-2: As per F5 recommendation big3d version should be same in all F5 products.

     

    Hope this will help. If still any question let us know.
