any custom materials that you worked with and worked on should have been saved to a server.
then when upgrading all you need to do is run the settings wizard to put all the file locations back to the servers.
that or go back and set each installation to point to the right locations.
Check your registry. The entries may still be there under an old version of SW

Custom_matls_091516_sw2016.sldmat or whatever as you named your custom material list
This would only transfer the material database and not the favorite list or the list you get on the right click menu on the material folder.
In order to share/copy that list to other machine use the reg key suggested by Matt Gortner
