Thanks. I checked this blog & there is note mentioned by Dolores which says we can have two projects one for Implementation & another for Maintenance Project.
1) In my case I am already using Maintenance Project for ChaRM. But now if I have to use Retrofit I need to have Retrofit system, so at this point if I add the Retrofit system in the existing Maintenance logical component is it Ok, will project be consistent ?
CREATE TWO LOGICAL COMPONENTS WITH NEW MAINT PROJ OR ADD NEW ONE IN THE EXISTING PROJECT BY CLOSING MAINTENANCE CYCLE FOR RETROFIT requirement
2) My another query is for Maintenance Project I am using Urgent Change & for Implementation Project I will use Normal Change. Will that matters for Retrofit ?
IT DOESN'T MATTER AND YOU BASIC IS CORRECT UC and NC for Maint and NC for implementation
3) Is retrofit works for both Normal Change & Urgent Change ?
yes it works for both type of changes
hope this helps
