My customer is currently using OVSD 4.5 SP12. I wanted to know if Service Pack Upgradation can help to get more custom fields for CI? Please let me know about it and also if it helps then please advice which SP should be upgraded? I was thinking to upgrade to SP23 or SP24 so that in future if they plan to migrate to SM 7 it will be easy to migrate. But please advise me will it be useful to get more custom fields for CI than what I have in SP12?
