  • Just want the easy upgrade (rather than download ISO) methods for vSphere 6.5 Update 1, also known as 6.5U1 or 6.5 U1? No problem, jump on over to:

    Today's big vSphere 6.5 Update release is a big deal in that many customers choose to wait for these Update 1 versions of any major vSphere version before upgrading their enterprise. Yes, to mee, it seemed that vSphere 6.5 was such a major change from 6.0 that it could have just as well been called 7.0. That nitpicking aside, the wait-for-N+1 customers and risk-averse home-labbers is over. Start your downloads, but be sure to read this entire article before you begin installing!

    Let's roll up our sleeves and have a look at all the great new vSphere features and fixes:

    For those of you into vSAN, there's considerable refinement that moving from vSAN 6.6 to vSAN 6.6.1 will bring.

    VMware vSAN 6.6.1 | 27 July 2017 | ISO Build 5969303


    Check for additions and updates to these release notes.

    There are many fixes, and a few new features. This article helps remind folks that the vSAN bits are baked right into the Hypervisor, so there is no separate download for vSAN 6.6.1, it's right in vSphere 6.5 U1! Also, anybody can now upgrade from vSphere 6.0 U3 to vSphere 6.6.1 / vSphere 6.5 U1,.

    VMware's Announcements

    From earlier today:

    added Jul 28 2017, another closely related post

    Don't forget to check out the deeply technical overview by Jeff Hunter and others over at StorageHub.

    If you are already at vCenter/VCSA 6.5.x and ESXi 6.5.x, then you can get vSAN bits today by simply installing or upgrading to vCenter/VCSA 6.5 U1 and ESXi 6.5 U1. Details appear (soon) for both new installs and upgrade.

    vSphere 6.5 Update 1 Prerequisites

    1. read VMware's vSphere Upgrade guide
    2. You will also need to do your homework before any major upgrade, even in a home lab. While all that goes into such efforts is well beyond the scope of this article, a great place to get started appears here:

    vSAN Prerequisites

    1. You will need the right hardware for the best experience, especially if you're expecting resilience and performance. Not just on the VCG (VMware Compatibility Guide) aka HCL, but also on the VMware Compatibility Guide for vSAN, featuring a caching layer made from SSDs of the proper write endurance paired with PLP/Supercapacitors, typically found in enterprise (costlier) flash storage devices
    2. You will need a vSAN license key
    3. Licensing was discussed recently here, with VMware EVALExperience ~being by far the most affordable way to dip your toes into to a 6 node hybrid vSAN (unconfirmed, but the license key should cover 6), albeit a bit behind on version. I'm hoping for updates to that program soon, stay tuned.~
      This has been [mostly] Fixed! That huge update story broke right here at TinkerTry first:

    It shouldn't be too long before the EVALExperience downloads links are updated to 6.5 U1. Keep in mind that you can always upgrade your 6.5.x version quite easily, seen below.

    VCSA baby! (NOT vCenter)


    My focus and yours should be on VCSA going forward, not the old school vCenter installed on Windows. That is why TinkerTry how-to guides generally don't include vCenter on Windows. I'm all in with HMTL5 UIs, and enjoy the ease-of-install, ease-of-update, and speed of this Photon OS-based appliance. See for yourself in the update videos.

    Easy Upgrade

    Here's the exact way that I got these two upgrades done safely and easily, with a focus on simplicity for smaller home labs, download and install is done with one command, which I tested using the latest BIOS and IPMI on Xeon D:

    1. How to easily update your VMware vCenter Server Appliance from 6.5.x to 6.5 Update 1 (VCSA 6.5 U1)

    2. How to easily update your VMware Hypervisor from 6.5.x to 6.5 Update 1 (ESXi 6.5 U1)

    What are you still reading this for? Roll up your sleeves, backup your VCSA and ESX, and get upgrading! Then come back and let us know how it went by dropping comments below the articles.
