I've upgraded a Management Server from R77.30 to R80.10 using migrate export/import. All went well. But after the import. In R80.10, i got one "validation error" regarding an invalid email address. As indication, it is said: Go to rule at layer "Implied First Rules ".
Looking at my implied first rules, some are VPN rules and some are firewall rules. Below are an example from each types. I cannot identify where this invalid email address is among these rules. Any hint or advice? Can it be complaining about the source and destination objects written "MembersGW.EncDomain@relateddomain"?
