Delete Version 3 Before Running Version 4?

If I upgrade from DEVONthink version 3 (“DEVONthink 3”) to the new final release version DEVONthink version 4 (“DEVONthink”), should I first delete the old version 3 before launching version 4? Or does this happen automatically? Or can they even remain installed together?

This doesn’t seem to be mentioned in the upgrade guide web page, unless I missed it.

Thanks.

This has been asked and answered. Please review the latest posts and search before opening new discussions.

I searched using the search function but missed that particular post.

But contrary to shrillek’s advice and as mentioned by Charles56 and Kinsey it isn’t covered on the upgrader’s guide page. I think it should be. One shouldn’t have to trawl through posts about the “beta phase”. It should be on the upgrade instructions page along with those other notes.

For anyone coming here and wondering what the answer actually is, it appears to be: quit and then delete the version 3 app, quit Safari (“as the browser extension could be loaded”), then reboot and install the version 4.

Then there’s all the stuff about new locations and so-on (which actually is on the guide page) (and, I guess, any Hazel rules etc., etc).

Please tell me if I’ve got any of those version 3 to 4 upgrade steps wrong.

Actually, the guide notes actually imply that you might have both versions installed, as they say:

Should you have both app generations installed, don’t delete DEVONthink 4’s Application Support subfolder as it contains the actual data files.”

Those handling the web stuff will have to look at this.

quit and quit Safari (“as the browser extension could be loaded”), then delete the version 3 app, then reboot and install the version 4.

That could be used, though it could just as well be “Install but don’t yet launch DEVONthink 4 yet.” as the first step. You may also need to open your databases in 4.

Would you really instruct someone to “install but don’t yet launch DEVONthink 4 yet” [sic]?

Doesn’t quite fit with your answer to Charles56’s question “Are DT3 users expected to install DT4 alongside DT3?”, viz: “No … at a minimum, delete the DEVONthink 3 application and reboot the machine”.

Of course, no way that was suggested merely to justify the confusing implication in the guide notes (the “web stuff”).

Yes and I certainly have in the past as well. Install does not imply launch.
