What can cause the HA pair to go Standby/Standby
We got Two Clusters (2x 4000 LTM) + (2x 6900 LTM - prod)
We are progressively migrating our configuration from 6900 to 40...

AltostratusCheck if you have vlan-failsafe configured on vlans and if the action is set to failover. If so, the vlan-failsafe action will try to trigger a failover when the bigip sees no traffic on the vlan. Check the logs to see for messages like
Sep 23 04:54:52 dc0-lab-ltm0a.test.com notice sod[5532]: 01140029:5: HA vlan_fs /Common/VLAN27 fails action is failover.

You will have to remove vlan-failsafe before making any changes to trunks, vlans or selfips, which affects the traffic flow.
