Failing import of content after upgrading u9 to u13

[ahlvertica]

We are experiencing a issue with importing content after upgrading the CMS. The user that did the upgrade does not have the issues, and we suspect its due to the fact he had a functional DB before the upgrade.

Im currently trying to setup the dev environment with a clean DB, and I can only import the Settings for the environment.
When trying to import content, the media succeds but when it gets to the content part, it instant fails with the msg:

"One or more errors occurred. (Found invalid data while decoding.)"

and the stackTrace in the importHandler:

We dont really have anything to go from here, so is there a suggestion on how to troubleshoot our issue and not just transfer the whole DB from the guy that has the working one?

I can see we are using the uSync 9.2.0, but I did try to bump that up to a 13.x version to see if that was the reason for the error, but no change was seen.

About your Site (please complete the following information):

• Umbraco Version: 13.4.0
• uSync Version: 9.2.0/13.1.5
• Browser Chrome

Hi,

We've done some investigating and we think the situations will be improved (but maybe not completely solved) in the v14.2 release of uSync (just released!).

What we have learnt

• uSync was using the delayed notifications feature of Umbraco - which deferres all publish / save notification to the end of the process for speeed/performance, but this was causing issues. where if one bit of content failed, but other succeeded the umbraco notifications seem to take exception and the successful pages never made it either (so you get no content).
• Individual content properties can cause the whole page to fail, this is still true, but we have put some better logging and UI elements in place so you can at least see these quicker and potentially get to the actuall error.
• Umbraco's own starter kit is full of invalid property data in v13 and if you use that to migrate to v14 you get loads of issues ! -
  this is because v13 is much more fault torerlant than v14 - if there is a bit of dodgy property in v13 things will still import but when you get to v14 that causes a more cirtical faulure :(

Hopefully if we can identify failures caused by changes in data we can put the code in uSync, we have places where we morph incoming property data, (in the mappers) and if there are specific cases we need to capture we can, hopefullt the new release makes that eaiser to at least spot and less castritrophic when it happens (although to be clear, thats v14 throwing the toys out the pram!).

Hey again.

Is there another way if we dont have a upgrade to v14 on the drawingboard for now? Seems like the usync v14.2 require a similar version of Umbraco for it to work?

Install failed (project: Web. CMS, package: uSync v14.2.0) Package restore failed. Rolling back package changes for 'Web. CMS'. Version conflict detected for Umbraco. Cms. Web. Common.

Hi,

Sorry, i think i got confused here, that comment related to a different issue! (too many tabs!).

In theory there should be no issue going from v9 to v13 - but i would make sure you had the latest version of uSync for the version of umbraco at each end (so v9 for 9 and v13.* for Umbraco v13).

If i was debugging i would start with .

• A 'clean' export on the v9 site to make sure you don't have an rouge files in the uSync folders.
• A copy of the uSync/Views and wwwroot folders over to new fresh v13 install
• An import there to see what happens.
• Checking the logs to see if that adds anything

If this doesn't help and you feel able, you could send over the uSync folder to me (kevin@jumoo.co.uk) and i will take a quick run through it locally to see if i can spot anything (this also helps us iorn out issues as we can feedback anything into the code).
