Migrating vCD with an External Microsoft SQL Database to vCD Appliance with embedded vPostgreSQL DB.

As per the workflow mentioned in the primary post, this is the 2nd step towards our upgrade.

Important notes and prerequisites:

Ensure the upgrade from 9.0 to 9.7 in completed successfully and cells are rebooted.
Create a New NFS mount point to be used by the new Deployment
If you want the new vCloud Director environment to use the IP addresses of the existing environment, change the IP addresses of the existing cells to temporary IP addresses.
Migration sequence consists of 4 steps:
1. Ensure the existing environment is version 9.7, this upgrade is mandatory. Refer to my last post.
2. Creating the new vCloud Director server group by deploying one or more instances of the vCloud Director 9.7 appliance. Refer to my old post.
3. Migrating the external to the embedded database.
4. Copying the shared transfer service data and the certificates data.

Procedure to migrate:

Before starting the migration stage Step-1 is to install new vCD Cells appliance version 9.7.
In my lab, i have deployed only 1 cell which will be primary named HRCVCD97.
As per the vCD 9.7 and later deployment requirement, it has 2 nic card on different sub-nets.

Step 1: Stop vCloud Director Services on all the old and new cells.
using following command:
“/opt/vmware/vcloud-director/bin/cell-management-tool -u administrator cell -shutdown“
confirm the password for administrator upon request.

Step 2: I choose a Cell named “HRCVCD9” as “Migration Source“.

Step 3: Configure External Access to the vCloud Director Database.
Configure/enable access from HRCVCD9 to HRCVCD97 (eth1) to the embedded db over second interface (in my case ens224)

Step 4: On HRCVCD9 – migration source, run the cell management tool to “migrate the external database to embedded Database of HRCVCD97″.

Step 5: After DB migration, it time to perform following actions on HRCVCD97 – Which is newly deployed cell:

Backup and replace the configuration data.
From migration source we are going to copy global.properties, responses.properties, certificates, truststore, and proxycertificates which are located at /opt/vmware/vcloud-director/etc/ and replace these files on HRCVCD97.
Special mention for file “truststore” which is applicable if New Cell is vCD 9.7.0.1 or later which i presume is all new deployments are.
Only back up the keystore file that is at /opt/vmware/vcloud-director/certificates.ks.
Reconfigure the vCloud Director service using the below command.
Start the vCloud Director Service.

Step 6: Clean up/de-commission of the OLD cells needs to be performed from vCD login page.
Once deleted, Power-off the VM and delete from inventory.
