How to Upgrade from Windows vCenter 5.5 to VCSA 6.5 including SRM

In last couple of days, I heard this question many times for below scenario. Since 5.5 is about to expire this month, so IT admins are upgrading their environment to new version of vSphere. Though going directly to 6.7 is something that do not meet N-1 requirement for most of the environment. Hence most of the admin prefers to put environment on vSphere 6.5.

Very first question everyone think about is –

  • Does upgradation path from vCenter 5.5 to VCSA 6.5 is supported? Answer is YES.
  • Does upgradation path from VMware SRM 5.8.1 to 6.5 is supported? Answer is NO. You need to upgrade VMware SRM 5.8.1 to 6.0 or 6.1.2, and then upgrade SRM 6.0 to 6.5.

Here we have details of existing environment and requirement which need to meet.

Existing Environment: –

  • Windows based vCenter Server – Version 5.5
  • Site Recovery Manager – Version 5.8
  • Replication Type in SRM – vSphere Replication

Requirement: –

  • Appliance based vCenter Server (VCSA) – Version 6.5
  • Site Recovery Manager – Version 6.5
  • Replication Type in SRM – vSphere Replication

Sequence to upgrade Windows based vCenter 5.5 to VCSA 6.5: –


If you are planning to upgrade your vSphere environment, follow this order to upgrade vCenter server, SRM, and vSphere Replication.

Overview of Upgrade order: –

  • Since vCenter server 5.5 doesnt have PSC server, you need to make sure that you install PSC when prior to upgrade vCenter server.
  • Upgrade PSC and vCenter Server in Protected Site.
  • Upgrade vSphere Replication appliance in Protected Site.
  • Upgrade Site Recovery Manager in Protected Site.
  • Perform the same steps in Recovery Site.
  • If you are using array based replication in SRM, you need to upgrade SRA in both site.
  • Once up gradation sequence has been done, verify vCenter server and SRM sites status.
  • Upgrade ESXi host in both protected and recovery sites.

Step by Step Guide to Upgrade vSphere Environment: –

Prerequisites: –

  • Download vCenter Server Appliance ISO image, VMware SRM 6.5 setup, and vSphere Replication appliance from VMware download portal.
  • Ensure that you have a windows machine from where you will initiate the installation.
  • Ensure to get SSO credentials and VCDB and SRM DB database handy.
  • Note down the details of ESXi Host where you will deploy VCSA appliance.
  • If you want to use the same name of vCenter Server which you are using currently, you need to rename windows vCenter VM with alternate name.
  • If you are using VMware SRM 5.8.1, then you need to upgrade it to VMware SRM 6.0 and then you can upgrade it to Vmware SRM 6.5.

vCenter Server Upgrade: –

There are two stage process to upgrade vCenter Server.

  1. Deployment of VCSA
  2. Migration of Windows vCenter Data to newly deployed VCSA.


Stage 1:

  • Now mount VCSA image ISO in any windows machine. Explore the ISO folder and navigate to VMware-Migration-Assistant.exe. Right click and click on Run as Administrator.
  • Follow the steps and provide SSO credentials.
  • Once you will get black screen with a message – Waiting for migration to Start, Switch to ISO folder again.
  • Go to vcsa-ui-installer/win32 folder and click on Installer and Run as administrator.
  • On windows screen, you will get four options.
    • Install
    • Upgrade
    • Migrate
    • Restore
  • Click on Migrate and follow the steps to complete the deployment of VCSA.

Stage 2:

  • Once deployment gets complete, you need to switch to stage 2. Here you need to migrate existing windows vCenter server data to VCSA.
  • During the data migration the Windows vCenter will be shutdown and the VCSA will be configured with its IP address.
  • Follow the steps and complete stage 2. Now you can access vCenter server using Web client.


Upgrade vSphere Replication Appliance: –

Download vSphere replication appliance and upgrade appliance by following below VMware document.

Learn SRM – Part 15 – Perform Real Recovery during Disaster Scenario in VMware SRM 6.5

In last article, we saw how to perform a test DR or you can say that Test Drill using Site Recovery Manager.

In this article, we are going to explore a live situation if you face a real Disaster then how will you recover Virtual Machines from Protected Site to Recovery Site.

Step by Step: –

  • Login to Site Recovery Manager Console.
  • Go to Monitor tab under Recovery Plan Section.
  • Click on Red icon.


  • Here you will get a different options. In test recovery, you didn’t had this option. But if you perform a real DR, then you have two options.
  1. Planned Migration
  2. Disaster Recovery
  • If you want to perform a real recovery during any Disaster, you have to choose option 2 which is for Disaster Recovery scenario.
  • Accept Recovery Confirmation and Click on Next.

Learn SRM – Part 14 – Perform Cleanup Activity in VMware SRM 6.5

Once our Testing has been completed, we need to run cleanup of the environment. Site Recovery Manager performs several cleanup operations after a test.

  • Powers off the recovered virtual machines.
  • Replaces recovered virtual machines with placeholders, preserving their identity and configuration information.
  • Cleans up replicated storage snapshots that the recovered virtual machines used during the test.

Step by Step: –

  • Login to VMware Site Recovery Manager Console.
  • Go to Monitor Tab and Click on icon highlighted in Red box.

2018-08-28 01_17_31-vSphere Web Client

  • Ready the Informational message. you may also choose Force Cleanup option if normal cleanup doesn’t work properly.
  • Click on Next

2018-08-28 01_17_34-vSphere Web Client

  • Cleanup Activity is ready to complete. Click on Finish to start the activity.

Learn SRM – Part 13 – Perform Test Drill using VMware SRM 6.5

In earlier posts, we have gone through with the Installation and Configuration of Vmware Site Recovery Manager. We explored both version 8.1 as well as 6.5.

We are no on final stage of our planning. SRM is ready for your environment. You can now plan Disaster Recovery Test to check the functionality. Here we are going to perform the same. We have the recovery plan configured according to our requirement, now let’s initiate the test drill. Remember that when you test a recovery plan, SRM uses the test network to test the VMs and keep Recovered Virtual machines in a bubble network. During test drill, your production Virtual machines will remain powered on and there is no impact on Production environment. Testing a Recovery Plan creates a snapshot on the recovery site of all the disk files of the virtual machines in the plan.

Let’s move to the Step by Step Guide to Perform a Test Drill: –

  • Login to Site Recovery Manager Console.
  • Go to Recovery Plans and Click on Recovery Plan you want to initiate. You can group your virtual machines in Protection Groups and later can add those protection groups to the recovery group. Now you will have choice which Virtual Machines you want to test.

2018-08-28 00_29_06-vSphere Web Client

  • Go to Monitor tab and Click on Green Run Icon.

2018-08-28 00_29_10-vSphere Web Client

  • Select Replicate Recent changes to recovery site. Click Next.
