High availability in 10.2 and 11.6

Question

Dear Expert,
  I've updated f5 1600 series loadbalancer in active standby mode.
  Recently I've updated standby LB to 11.6 from 10.2. After upgrading, I noticed high availability is gone.&nbsp;
Do I need to config HA manually? if yes, how?&nbsp;
Is there anything I need config manually? if yes, how?&nbsp;
Pls help. I'm new in f5.&nbsp;
Best Regards. 
 Banik &nbsp;

HA changed quite a bit between 10 and 11, see this document:&nbsp;
https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-active-standby-upgrade-11-1-0/1.html&nbsp;
it (mentions 11.1, but same goes for 11.6) explains about the new method with device groups and traffic groups. those should have been created during the upgrade process, but if they aren't you will know where to find them.&nbsp;
