BINARY UPGRADE: SM9.33.P3 to SM9.41 classic


Can anyone suggest best upgrade path (binary upgrade only please) for SM9.33.P3 to SM9.4x please.  We are thinking of SM9.41.  Client only has limited budget for a binary upgrade.  We want to introduce them to the new look and feel of SM plus we're thinking if we can "slowly" introduce some new functionalities that won't require a lot of work.

Would appreciate any feedbacks.
