Facing packet dropping issue after imported configuration.

[sujithGovindaraj]

 The issue is currently planning to migrate PA220 to PA440.

We have imported the configuration file from PA220 to PA440,  The network is down and facing packet drops 

Then we disabled the HA and disabled the ECMP configuration, but the same issue persists.

We took a backup from PA220 and then imported it to PA440 after 6 hours we faced a packet dropping issue and networking down no internet. kindly assist us in resolving the issue.

Thanks in advance!

Hello @sujithGovindaraj 

I would suggest taking a packet capture and checking the global counters to understand what is causing the packet drops.
