Automation scripts for upgrading Small Footprint TAS for VMs 6.0 to 'full' TAS for VMs 6.0

Products

• VMware Tanzu Application Service for VMs

Issue/Introduction

If you have installed Small Footprint VMware Tanzu Application Service for VMs, you can upgrade your installation to full TAS for VMs. The upgrade process preserves most of the existing tile configuration and transforms the existing Small Footprint TAS for VMs into full TAS for VMs.

Environment

Product Version: Other

Resolution

This article contains a download link to Bash scripts that can help automate the process of upgrading a Small Footprint TAS for VMs 6.0 deployment to a 'full' TAS for VMs 6.0 deployment. 

Please refer to Upgrading from Small Footprint to full TAS for VMs documentation for detailed instructions on how to use these Bash scripts in your upgrade.  Please also refer to the sections that describe the upgrade process and safety considerations to ensure that your upgrade is as smooth as possible.

Small footprint migration automation scripts (for the Assisted Upgrade section of documentation):

• The validate_sf_tas_deployment script runs against a Small Footprint TAS for VMs deployment and does not alter the deployment in any way. The script scans the deployment configuration to determine if all requirements for the upgrade process are met, and prints out any missing requirements for you to correct. When the script executes successfully, the deployment is ready to be upgraded to full TAS for VMs.

• The reattach_sf_tas_disks script runs against a full TAS for VMs deployment after the deployment has been upgraded from Small Footprint TAS for VMs. The script scans the deployment to ensure that the database and blobstore have at most one instance, and if so, automatically stops all VMs, reattaches the Small Footprint TAS disks, and restarts the deployment. You can run the script multiple times if necessary. It creates log files to determine which instances already have disks reattached, and skips those instances in future executions. When the script executes successfully, the upgrade from Small Footprint TAS for VMs to full TAS for VMs is complete.

These scripts can be found in the attachment 6.0_sf_tas_to_full_tas_upgrade_scripts.
