Migrate from Windows base vCenter PSC to VCA PSC

I tried how can migrate from windows base vCenter to linux base VCA server. In this post I would like to share my experience.

Fortunatlely the migration process reconize our vCenter environement, and it is able to determinate wich type of vCenter (PSC or not) want we migrate.

First of all we can runing VMware Migration Assistant on source vCenter server. You can find this app on vCenter install media.

This console base app will check our server is meet the requiments of migration. Eg.: in my lab environment i didn’t use gateway, becouse i used same subnet for all servers. This tool notice me, this is an error!

When everithing was fine, you will see “Waiting for migration to start…” message end of lines.

VMFS 6 Upgrade

We have tested our new demo Dell EMC Unity 400F storage and we conneceted this test to our vSphere 6.5 test. 2 in 1 solution I really like it 🙂

I red White Pepaer about vSphere 6.5 Storage, and i find in this article, VMware introduce new VMFS. I want upgrade our VMFS version to latest version. Like always i have started search upgrade option, but i couldn’t find it.

I started read about whats new vSphere 6.5 Storage, and i find this in VMware Document Center: https://pubs.vmware.com/vsphere-65/topic/com.vmware.vsphere.storage.doc/GUID-7552DAD4-1809-4687-B46E-ED9BB42CE277.html

End of this article I recognize why I couldn’t find any upgrade button 🙂

“Upgrade. After you upgrade your ESXi hosts to version 6.5, you can continue using any existing VMFS5 datastores. To take advantage of VMFS6 features, create a VMFS6 datastore and migrate virtual machines from the VMFS5 datastore to VMFS6 datastore. You cannot upgrade the VMFS5 datastore to VMFS6.”

 

Enable SSH VMware vRealize Operation Manager (vROps 6.x)

We have investigated our problem with VMware Support and they want run a query in Postgres database. Usually I use Putty for SSH connection, but before I could do this I should on the ssh on vROps:

  1. Open vROps Console and press “Alt+F1” to switch console
  2. Type “root” user
  3. In default vRealize root user hasan’t password
  4. Press enter for Old password and the promt will change New password
  5. Type new password and type again
  6. When we are able to login by root type: “chkconfig sshd on”
  7. Start service: “service sshd start”

Go back to Putty and connect to vRealize Operation Manager by ssh.
