upgrade vCenter 5.5 to 6.0

  • hi guys

    I have several datacenters 7 in fact different physical locations and all of then in 5.5

    I need to upgrade from vCenter appliance 5.5 to 6.0, I’ve asked support but they are not sure if upgrading from 5.5 to 6.0 will broke all replication and I have to recreate from scratch

    they only send me these 2 links




    so basically my question:

    from you experience on a day to day basic has someone upgrade from 5.5 to 6.0? what happens? the replication only is down for the time vcenter upgrades or I need to reinstall ZVM and recreate VPGs

    thanks a lot


    thanks a lot Harry,

    I got lucky and I have two servers that I am going to use to setup a lab so I will be installing vmware 5.5 —– migrate to 6.0 and I will let you know guys

    I am not sure if that checkbox option is available during upgrade so I am going to test in my lab




    Just wanted to add that I went through the upgrade process a few months back using the migration utility from VMWare. We moved from a windows based deployment with SQL to the VCSA with embedded, we had no issues with zerto replication during this process.


    just wanted to update

    I had VCSA 5.5 U1 – Linux based – I updated it using the wizard to 6.0 and even when a new VM – VCSA 6.0 – is created all the information is kept and the replication continued without a problem


    This is a follow-up for Brian S. I’m looking to do the same vCenter upgrade as you, v5.5 on Windows, using the migration tool to go to 6.0U2 on an appliance. It all looks good to me, but my question for you is, is your vCenter joined to a domain? If yes, how did the migration handle the domain membership of the new vCenter appliance? I assume you used the same name as your 5.5 vcenter so Zerto would continue to function. Did the migration tool reset the computer object for you? How did this work? Thanks.


    Sorry, just seeing the post Matt. Yes, my windows virtual center was joined to the domain and during the migration wizard you are prompted for AD credentials so that the process is seamless. You should not need to take any other manual actions regarding the computer object if the credentials you provided have the required privileges to perform the action.

    The below KB speaks to this a bit.
