Do it the easy way install sentinel on the new computer update the database on the computer then read the scanner and save the file.
That would work if
all Favorites lists currently in Sentinel on the Windows 7 have been downloaded to the scanner. But if only some of them are, then the manual file transfer captain suggested would be the best way to proceed.
For that matter, if the OP has a card reader, then use the Windows 7 pc to write all favorites lists to a spare SD card (after using the 'clear user data' to set up the card). Once all lists have been downloaded to the card (in a card reader) then eject the card reader correctly from the Win 7 pc, and plug the reader into the Windows 10 machine (after Sentinel has been installed). Then use 'read from scanner' in Sentinel to get all the lists moved over.
I have several dozen Favorites lists set up. Some for normal use in my area, some for areas I go to often enough to create a specific list, and other lists set up for a single "new" system that I'm trying to document. Gneally, I have a half dozen or fewer lists (at one time) on any of the scanners.
