Bulletproof upgrade to DT4 (and rollback to DT3)

Hi all,

Since I initiated this topic, I would like to share my experience with the upgrade.
First off: I’m not saying this is the right way, I’m just sharing what I did and what I noticed, in case someone find it useful.

How I did upgrade DT3 → DT4

  • closed Safari
  • Devonthink 3: closed all databases ; Closed Devonthink 3
  • restarted the MacOS
  • zipped Devonthink 3.app → copied the zip to Desktop
  • moved Devonthink 3.app and Devonthink 3.app.zip to from \Applications folder to the Bin (“Move to Bin”)
  • downloaded Devonthink4 from “customer account” and installed it
  • on Welcome Screen clicked “Install AddOns”
  • Opened databases
  • all seems ok, databases mounted Ok

What I see / find on first look:

  • tested drag n drop of some email from mail.app into Inbox in Finder → works ok
  • some Alfred (apple) scripts easy fixed with changing
    tell process "DEVONthink 3" to
    tell process "DEVONthink"
  • Alfred scripts using tell application id "DNtp" are working ok, no changes needed
  • all items in Devonthin Inbox(es) are still there from DT3
  • smart rules / searches are there
  • Preferences (like font for rtf files) ARE NOT preserved
  • Label Names ARE NOT preserved
    • for ex for Red Label I’ve changed the name to Burning in DT3, but now it’s not preserved
    • however items in database which were labeled, are still labelled with same color as before (I think :slight_smile: )
  • Not all scripts are there, for example in Export Folder

For the last bullet point I created another post: DT3 → DT4 upgrade: Scripts Folder differences - DEVONthink - DEVONtechnologies Community

What else I did on test Mac

(! > Pls note this is on a test Mac, and not production < !)

After installing DT4, opening, mounting databases, dropping some emails from mail.app I did the following:

  • closed DT4
  • zipped DEVONthink.app from /Applications folder
  • removed the zip from /Applications folder
  • restarted Mac
  • returned back Devonthink3.app into /Applications folder
  • started Devonthink3.app
  • opened databases

I didn’t do too much messing around but it gave me some peace of mind that I can run DT3 and mount the databases.

Hope this helps.

Cheers
