I have several ongoing projects in Dorico 4 at the moment. If I upgrade to 5 will they open up okay?
That’s certainly the idea. There is a thread from this morning in which a very large project done in Dorico 4 was not opening in the latest version, but that’s definitely an outlier.
All of my Dorico 4 files are opening just fine. (Even a file that I hadn’t opened since 3.1!)
Yes: opening old projects in new versions is fine. There have only been a couple of times when new features have directly affected things, such as the change for Lyrics to Paragraph Styles.
If you’re in the middle of a job, then that’s the best time to switch, as you will be polishing it and checking it before it’s complete!
Great news! I will mooove myself over to the product page and purchase.
