We are running vCenter 7.0 U2c build 18356314 and 7.0 U2d build 18455184
I want to patch these vCenters, which is the best patch and build so that i can go ahead.
Thanking you in advance
As your post needs moving to the area for vCenter Server, I have reported it to the volunteer moderators.
You'd usually go with the latest patch.
This may however depend on your environment, i.e. any registered solutions, or 3rd party applications for which you should confirm that they support the version/build that you are going to update to.
