thanks for your quick reply - yes I did store and RE-store the .dtbase2 files there as a backup - for both my normal databases and also the special "inbox’ database which is stored by default in the Devonthink application support folder.
I guess my fear is that files in my database have just ‘vanished’ without a trace into the ether without my noticing from this process… I use my database for medical literature and tax files and lots of things so I have been worried
edit: I should also state as feedback that this issue arose due to following the instructions here:
DEVONtechnologies | How to Migrate to a New Mac.
In hindsight maybe they could be revised to explicitly state "don’t use dropbox as the mechanism to transfer files to the new machine’ which is basically what I did! - (I know the instructions refer to external drive but I didn’t have one handy… so I thought - well I can use a cloud… drive… )
anyway I am a goose
Unfortunately I no longer have access to the pre-migration database files
