I'm upgrading my LTM pair (Primary/Standby) i2600 from 12.1x to 14.1.x. Will I need to reset trust between devices to syncronize?
If I remember I had to once after a software upgrade, I thought you would only need to perform a reset if you replacing hardware for example but rather a software upgrade like the above you shouldn't lose trust? I'm interested what decides a trust reset between a pair.

The trust will not break during the upgrade.
You'll be starting with the upgrade on the Standby as usual. But the configs wont get synchronized (if there's any changes happening during this time frame) - as the SW versions will be different.
Then you'll make the standby as Active and start the upgrade on the other box. The trust will be same and finally devices will be back to In-Sync.
