ASA Statefull Connection re-sychronization

I have a question regarding how the ASA re-synchroniztions connections after a failover pair returns from an active/active situation due to loss of connectivity between the 2 units.

We will be separating an active/standby pair between 2 data centers with a dedicated high bandwidth low latency link.

When the link between the 2 facilities both devices (primary and secondary) will become active. I understand the behavior when the link fails, but we have 3 possible scenarios that could exist when the link is re-established.

1. When Primary is maintaining accurate connection tables and secondary has no connections

2. When Secondary is maintaining accurate connection tables and primary has no connections

3. When both devices are maintaining active connections.

I need to understand how the connection tables will look and which connections will be dropped and need to be re-established after reconvergence.

thanks in advance
