How to check modified files/config before replace

[AkiYa]

Hi all,

I have a cluster of two 6700 gateways to be replaced with brand new 9200, unfrotunately these old gateways have been managed by an external supplier for years and I'm quite sure they did some changes in files (ie. table.def) or enabled/disabled some configurations.

Is there a way to find exactly what has been changed compared to a default configuration?

Or what do you suggest to keep these changes in the new devices? 

thanks!

Was this a Full HA cluster (without external management) or with external management?
Believe you can run the pre-upgrade verifier tool to get this information: 

$MDS_FWDIR/scripts/migrate_server verify -v R81.20 -skip_upgrade_tools_check
