Hi Jim, I did this migration 2 days ago following your instructions. Everything seemed to work except I noticed that the Date Modified attribute of several hundreds files was set to a same point of time, which was probably after the time I opened all databases in DT.
I noticed this change because when I re-enabled iCloud Sync in preferences, there were a large number of upload to iCloud which got me suspicious, since there shouldn’t have been any local changes to upload, only download changes from iCloud was expected (I’ve saved new items to DTTG from iPad that needed downloading.)
I’ve made a smart group selecting files from all databases whose Date Modified was set to the mentioned time, the number of which is 293 (screenshot below). As you can see, those files have various Date Created and Date Added, but all the same Date Modified. I’ve also checked a sample of items for the real modified time of the underlying files. It turned out the modified time as recorded by the file system looked plausible, untouched, and in line with the Date Created.
Any thought on this?
