Hi Ravi,
For uploading files(.txt) in GRC 10.1 the files will not contain any system information . please go through below link for format required for uploading files
In your case you are having 6 logical systems and 2 Cross Systems and 10 Connectors for 5.3
Similarly in GRC 10.1 create 6 logical connector group and add relavant indiviual connector in to it.
For example - logical connector group will be X_Logical and it will include relavant system
system1
system2
system3
...
while uploading files you can select logical connector group and upload those files. all the risk will get applicable for those systems which you have included in logicval connector group.
whereas for Cross system you will include cross system in to cross system group but while uploading files you can upload it those 9 files againts indiviual system
While doing risk analysis system will detect the cross risk.
For system which are not relevant to logical and cross system you have to upload the files by selecting specific system.
Regards,
Rakesh Kirve
