How to change SCCM Cache path during SCCM Client upgrade

Hello,
We are upgrading SCCM client from CB 2002 to CB 2006 so during upgrade we wanted to update the CCMCache path and CCMCache size if it is not appropriate.
We are using PowerShell script for client upgrade and we have used “SMSCACHEDIR & SMSCACHESIZE” parameters for installation command but they are not working.
As per below MS article “When you upgrade an existing client, the client installer ignores this setting”
https://docs.microsoft.com/en-us/mem/configmgr/core/clients/deploy/about-client-installation-properties
So, is there any way to update the CCMCache path and CCMCache size during client upgrade?
Please advise.
