vSAN on vSphere 6.0 and vSphere 6.5 – Upgrade path – there are dependencies..

A few days ago VMware released the new version of vSphere 6.0 Update 3. – As you would expect this version also contains some awesome patches for vSAN, which will make it more stable and more performant. – see the ESXi 6.0 U3 Release notes! Great stuff. – But take care there are dependencies. As there are currently two release tracks of vSphere (6.0 and 6.5) which are updated regularly – there are slight differences in vSAN versions and sometimes you cannot easily upgrade from a vSphere 6.0 version to a 6.5 version if you are using the latest vSAN versions of 6.0. – Sounds confusing? – Yes it is somehow.

And it is right now. If you are going to update your vSphere 6.0 to U3 today  – then you will have to wait for vSphere 6.5 U1 if you want to upgrade to 6.5. – and a possible release date for 6.5 U1 is somewhen in summer or autumn? – This means if you plan to upgrade to 6.5 before summer, you should not update to 6.0 U3 today.
