My client is having this problem where they upgrade their EP6.0 to EP7.0 and all their customized ESS become the standard ESS. As far as i understand, we need to re-implement modifications for the New track. (pls correct me if i am wrong). As told by my client, the old Track which contains those customized ESS has been corrupted.. Is there any way i can save the track back or by any other means i can get back the customized ESS source? (they are now having 2 EP in their development server, one is EP6 one is EP7) Thank you!
