Change datasource in .lyr files in specific folder

[JoseSanchez]

Good afternoon everyone,

We have a folder  with 175 .lyr files. All .lyr files are pointing to an SDE instance and we need to change each lyr data source to point to another SDE instance.

I am looking for a way to do that in python where I can loop through all files in the folder and change their datasource.

Thanks

Does any have the script to change the datasource in SDE to another on?

My script isn't working
