Upgrading Problems - Can we help?

This is a copy of the text posted in: nodejs/user-feedback#116 which was posted Oct 26 2018:

As Node.js 10.x becomes LTS next week,now is a good time to consider upgrading.

We understand that there are stometimes issues when migrating to a newer Node.js major version.
One of the things we have heard is that this can be due to a module in the dependency chain that is not being updated.

We would like to gather some feedback and better understand how we can improve the migration experience.

Sme questions we would like to float to the community:

What challenges do you have when you upgrade to a newer Node.js major release?
Have all modules you depend on been updated?
Which specific modules do you have problems with when upgrading. And more specifically are there any modules preventing you from migrating to 10.x?
Are you a maintainer that is overwhelmed and you are not able to update your modules anymore?

Start by reading the copied discussion in nodejs/user-feedback#116 and reviewing the migration questions in this issue. The issue does not name files, tests, or a specific change; it would need an agreed, concrete maintenance or migration action before completion could be measured.
