Exchange 2013 Updates

I want to get our Exchange 2013 up to the latest version.  We are currently on 15.0.516.32 and I see the latest version (so far) is 15.0.995.29.

Can anyone suggest an upgrade path?  Has anyone gone from my version direct to the latest or should I go in phases (etc).  I was thinking of just installing SP1 and then the couple updates after that.

This is the info I have on versions - 

Any advice would be helpful.

that is the RTM version

I see the latest version (so far) is 15.0.995.29

that build is CU6 released over a year ago; CU10 is the latest (15.0.1130.7)

I was thinking of just installing SP1...

SP1 is the same as CU4 which was released in february 2014 and is long out of support
you can go straight to CU10; they are cumulative
