Update all packages in msdb

Morning Guys,

I have like 500 packages deployed under various sub folders in msdb. In each of these packages we have package configurations enabled. Package config type is XML config. It uses environment variable to locate the config file and then reads connection string from it.

I want to update every deployed package to change the name of the environment variable configured in XML package configuration.

Can someone please guide on this?
