Deploying CloudFormation stack template for migrating VPC Private Link infrastructure

Overview

You can now have an enriched software deployment experience with Druva's new global discovery service. All the workload agents will now connect to this discovery service and help us intelligently change to a region and geography-specific software deployment.

Any upgrade to existing AWS PrivateLink enabled Druva AWS proxies will cause your AWS proxy to lose connection with the Druva disaster recovery (DR) services. Consequently, you will not be able to submit any DR jobs. To avert this situation, update the Route 53 records and VPC Endpoints associated with the AWS proxy by deploying CloudFormation stack templates. For any further assistance, contact Support.

Pre-migration steps 

Upgrade the AWS proxy to the latest version.

 After you migrate to the new deployment, create a new stack for migrating your VPC PrivateLink infrastructure to the new environment.

Next Steps

  1. Monitor the stack to see if it is created successfully.

  2. Refresh your Management Console to see if your proxy is able to connect to the target deployment where you want to migrate.
    For any issues, contact Support.

  3. If Proxies are not in a connected state after migration, do the following:

    1. Login to the AWS proxy.

    2. Update the /etc/Phoenix/DR/Phoenix.cfg file with the server URL of the new deployment and append prefix ap1 in the server URL. For example, SERVERURLS = [u'private-ap-southeast-1-backup-ap1-phoenix.druva.com:443']

    3. Restart the proxy.

    4. Refresh the Management Console and verify all proxies are in the connected state

  4. Delete the Cloud Formation stack that you created. For more information, see Deleting the Cloud Formation stack.
