I am new to an organization that is making the move from SP 2010 to SP 2013 to SP 2016 to SP 2019. These are all on-premise versions. The site collection has almost 3500 sites. There are lots of customizations - webparts that include more content editors that point to both jquery and html files.

For testing purposes, a team upgraded from SP 2010 to SP 2013. Nothing broke - yet. My concern is when they migrate to SP 2016, and the modern pages are turned on - content editor webpart does not exist in modern pages - SPFx rules. What happens on those pages where content editor webparts have been used for purposes of pointing to files? Is there a document for the best practices?

SharePoint 2016 does not have modern pages. The first step you need to take prior to migrating to 2016 is to run Upgrade-SPSite on 2013 which will change from v14.5 to v15 sites -- this often does break customizations, so you'll need to do this in a test environment. Transitioning from 2016 to 2019 will not change any site (though some customization may break, just depends on what they are).

Sites are never upgraded to modern. That is a manual process which you can choose to do once you get to 2019.

  • Thank you for your response. I have been informed that the Modern page feature will be manually turned on; I will not have a choice. It is going to happen. My question still is, is there any documentation on developing a good plan to go about and tackle these things. Like I wrote - I'm new to this organization. I did not create this conundrum.
