Reconciling Tag Names across Azure

Anthony Watherston has an interesting script:

During a recent cost optimization workshop with a customer, they mentioned that although they had some tagging policies in place there was no consistency of tag names across the Azure environment. This post introduces a script to remediate this and remove some confusion from your tagging strategy.

The customer was trying to ensure that all resources were being tagged with a cost centre tag. Some of this was automatic and some was done manually by people. While there was a policy in place to control this in the future, they needed a way to remediate the existing resources.

This is really useful if you have enough information to create a to-and-from mapping. It won’t automatically understand anything, so you’ll need to do the digging but it will do the renaming.
