Upgrade from SCM 4.0 to SCM 7.0
Need quick help from your end.
What would be recommended: Doing an upgrade from SCM 4.0 to SCM 7.0 or doing a fresh SCM 7.0 implementation? I understand that we cannot directly upgrade from SCM 4.0 to SCM 7.0. Rather, we have to go in two steps. For example- SCM 4.0 to SCM 2007 and then SCM 2007 to SCM 7.0.
What are the criterias that should be considered for deciding preference of fresh implementation over upgrade?
Also, it would be useful if you can share your experience with upgrade from SCM 4.0 to SCM 7.0, specially approach taken.
