How to rename an Alias?
Would expect folderitem.ignorealias.name (or something like that) to work. Any suggestions?

Get the folderitem via trueChild or trueItem without resolving and then change name.

" This item was deprecated in version 2019r2 .
Please use FolderItem.ChildAt as a replacement."

But will make it work using this. Thanks!

Using API 2.0 is also fine

Pass false for the followAlias parameter.
