Hi, I have an Umbraco 13.13.0 site which I’ve installed Umbraco Deploy On Premise on to. Ive then exported the entire site to a zip file via Deploy. I then have a Umbraco 17 site, with Umbraco Deploy On Premise installed and I copy the zip file in to /umbraco/deploy/import-on-startup.zip I’ve al…

So, it looks like small chunks is the way forward and also doing it manually instead of the import-on-startup.zip Thanks everyone for the help. In case anyone else comes across this with similar issues - Clean Umbraco 13 with Umbraco.Deploy.OnPrem Umbraco.Deploy.Contrib Then do a manual export …

And then typically - it now works. I just commented out some code that was throwing error and moved the Deploy Migrators to the top of my Composer file. Not sure which was fixed it, maybe a combination of the two. I’m going to rerun the deployment importer again on a clean setup just to make sure I…

Curious about the solution. I’m going to need to upgrade some old project that still uses Nested Content and macro’s and MediaPicker < 3 instances, so I’m curious if this is the way!

So I’ve tried a few options and this seems to be a possible. Just testing something again to see if I can replicate the fixes. My rough plan so for is : Install a clean Umbraco 13 instance, install Deploy, point it at the website database, this means the database is upgraded to the latest 13 vers…

Yes in my opinion that is a very sound plan: update the database first, then the code.

Annoyingly, for some reason I can’t get deploy to kick in every single time. So just now I have a file called import-on-startup.zip which “should” get read by Deploy since it’s within umbraco\Deploy\ folder however, it never gets deleted / archived. I’ve even updated the appsettings to see if that …

Looking back at your comments and stuff have you torn apart your code and put some logging in so each time it’s does a migration and fails you can get useful information also if in doubt take it out have you tried doing each of the migrations separately to see if you can isolate it to a specific …

So I’ve been doing a lot of similar migrations to this recently except not using the “Deploy on startup” side of it because I found a lot of the time migrators were falling over themselves a lot trying to do Schema + Content together. The bit of advice I was given in the past is to attempt Schema o…

Great! Thanks @TomChancer - Im actually in the middle of chunking stuff up in to small imports and doing a manual import via the “import” menu option in the backoffice. Hoping that helps :slight_smile:
