How to redo modifications when new ESS MSS SP is imported
Current Systems have SP 14 version of ESS/MSS in the landscape. Lot of customization is done in-house on these standard WebDynpro components. Now planning to import xSS SP18. In order to do the same, we are listing the modifications done on the old install and redo all changes on the new SP18 (as suggested in ESS/MSS cookbook). My concern is this approach invites manual errors and too cumbersome to redo all the changes from past 2 years. Is there any better approach using the configuration tools NWDI/ DTR/ CMS.
Please suggest with your inputs while implementing in similar situations.
