The easiest way is to change any script that targeted older versions of Evernote to use Evernote Legacy. For example,
tell application "Evernote"
set theSelection to selection
set theNote to ((properties of item 1 of theSelection) as note)
set linkURL to note link of theNote
set the clipboard to linkURL
end tell
can be changed to work with Evernote Legacy by changing tell application "Evernote" to tell application "Evernote Legacy". By the way, this script creates a "local" link to a note in Evernote, that can be pasted into documents on the same machine to reference the currently selected note.
