I've spent the day doing full backups of all my projects and saving copies on OneDrive for extra peace of mind.
I've also read everything on the Knowledge Base and the Calico site about things to bear in mind.
Last time I upgraded from an earlier version, I made a mess of saving my settings so this time I've decided to ignore all my previous settings and start afresh. Is that a daft decision? I think it would be easier for me to set myself some new settings based on the new tools and layout rather than carry over a hotchpotch of my old ones.
Change isn't easy when you're old and lacking in confidence!
