I have another question, and not sure if this is the group to post to.  In one of our Salesforce ORGs we have not switched to Lightning yet, but are planning on doing it at the end of May.  The Lightning Conversion Utility for JavaScript buttons didn't convert the sforce.apex.execute() calls that were in the Java Script buttons.  We opened a ticket with Salesforce and they logged it as a known issue with no workarounds.  I was wondering what are the steps to manually convert the sforce.apex.execute commands to lightning. I've seen different comments from bloggers but nothing from Salesforce.
