Using DLConversionV2 to migrate DLs of all kinds to O365

Hello all, there are similar threads related to converting DLs (plain ole DLs, Mail Enabled Security Groups, DLs with nesting, DLs used to give SendAs/Full Access) to Office 365 however I'm curious to hear from folks that are using the DLConversionV2 script and how successful (or perhaps periled) they were. I'm testing it and working through the kinks in a lab. Please share the good/bad about the script. If folks have used other scripts with success what where the names? 

We have a bunch of DLs of all types to move to Office 365, I have not moved any yet in production. Soliciting feedback to hear how others completed the tasks or are completing the task.
