Fail to change rulebase after an upgrade to R80.20

[Gilles_Lerat]

Hello Checkmaters, 

Yesterday, I started an upgrade from a R77.30 Management Server running SPLAT on an ESXI VM to a R80.20 Management Server, through the R80.20 Migration tools. 

The migration apparently succeeded and we were able to push the security policy to a new set of appliances. 

However, it appeared that we are not able to change the security policy. 

We get the following error message :

I search on Supportcenter & Checkmates, and could not find any reference to that specific problem. 

We can still make change to the Global Properties. The problem appears limited to the Network Policy. 

Thanks everyone for your help. 

Best regards,

Best to open a TAC ticket so we can properly investigate it.
