Do all Enterprise GIS components need to be the same version?

[Jay_Gregory]

I have a ArcGIS for Server site 10.3 (two machines, clustered), and plan on installing web adapter on our load balanced web services as well as one instance of Portal on a separate machine.  I'm waiting for some bug fixes for server coming out in 10.3.1, and was curious if it is recommended to wait for 10.3.1 on Portal and Web Adapter too, or if 10.3 will be sufficient.  Also, it is allowed to have 10.3.1 server installation but 10.3 Portal and Web Adapter installation or do all three need to be kept at the same version?

Thanks!

Also when is expected release of 10.3.1?

I assume 10.3.1 won't be out for a while because 10.3 was released in the middle of December, 2014.  For compatibility see this article. It's for 10.2 but I'm sure it still applies to 10.3

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

Hope this helps.
