Potential impacts when running ACS Migration Tool?

[matsiege]

Are there any potential impacts, such as performance/load, to running the tool against a live ACS deployment? Are there best practices for running the tool? ie: running against secondary instances or only during offload hours?

Here is a wealth of knowledge on the subject:

ACS to ISE Migration

Hint:  Do not do this on a production instance of ACS.

Thanks Charles. I noticed there was a recommendation in one version of our migration guide, but not the other. Thanks for clarification.
