I can’t comment directly as I am a windows user but my upgrade to 2019.2(1860 the preview build I am currently running) from 2017.10(1706) is not giving me any problems.
If your upgrade is a free upgrade, you could do an EXPORT BACKUP of your 2017 data set, put it in a safe place, then upgrade from https://infinitekind.com/preview
And try things out for a short time.
If you hit problems, very unlikely, uninstall 2019 and reinstall 2017 from https://infinitekind.com/download_2017
and restore from your 2017 backup.
