That suggests that you had some kind of undetected data corruption, which is one of the things that Save a Copy helps resolve. The other would be to perform a re-indexing of the file.James Culbertson said:I was able to finally migrate my Quicken Mac 2007 data file to Quicken 2019 (thanks to Quicken technical support) by "save a copy" into a folder on the desktop, and this imported fine. All other methods failed to import.
First, Quicken is no longer owned by Intuit but is a self-standing company since April 2016, so you would be contacting Quicken.com ;-)James Culbertson said:I could not "save a copy" on High Sierra (due I think to the APFS drive format). I used an old laptop with El Capitan (and HFS+ drive format) to do the "save a copy" which was what worked for me. You may need to do the same. But I would call a tech support person at Intuit; they were very helpful.
As James points out below, the issue has to do with the fact that backup features of QM2007 are not compatible with Mac High Sierra (OS 10.13) or higher when using an APFS formatted drive. The solution is to have the original data file AND any backups stored on a HFS+ (Mac OS Extended) format to use these features. This can be accomplished using an external drive or using Disk Utilities to create a HFS+ partition.Simon Rudyard Parker said:This is all well and good, but when I try to safe a copy of my Quicken 2007 file I get the error message "Unable to erase partly copied files" and it aborts the file creation effort. I get a couple folders, but no copy is created. I can create a back file .qdfm. Is creating copy or creating a backup result in the same .qdfm file creation? I just want to make sure I can update from Quicken 2007 for Mac into the Quicken 2019 before I commit to invest into updating my SW. I am running MacOS Mojave v10.14.2.
