VPN issues after migration 77.30 to 80.30

[BKYDCPSC]

Hi,

ive done a simple migrate export of a 77.30 management server, and imported on a clean 80.30 VM.

. No hostname or IP changes. 

after initial migration, we had no issues. Over the weekend, VPN tunnels have now gone down.

No policies have been pushed since migration. SIC was never reset as I believe you don’t need to.

any pointers?

gateways still on 77.30
