You can upgrade directly to 5.3.x
I'm a little confused by the OE Revision Matrix. All 3 of my SANs are currently running on OE version 5.2.1.0.5.013, and I would like to get to the 5.3.0.0.5.120 version. Can I go directly to the newest OE, or do I need to stage the 5.2.2.0.5.004 version first?  Thanks in advance!
