UCS release to update to


UCS release to update to


I'm currently working on VVX 300 with UCS 5.3.0 and I want to upgrade UCS version.

I saw that 5.5.3 was released after 5.6.0, so is more recent than 5.6.0


Do i have to upgrade to UCS 5.6.0 or 5.5.3 ?

Do the UCS 5.6.0 include the fixes of the 5.5.3 ?
