We are going to update our CQ 5.6.1 application to AEM 6.2. We made a lot of changes in our code and tested it on new test AEM 6.2 environment.
And the main question for us now - how to update prod system to AEM 6.2? I saw a lot of documentation from AEM (like https://docs.adobe.com/docs/en/aem/6-2/deploy/upgrade.html )
but we still confused what is real benefit of upgrading in place to AEM 6.2 instead of setup new AEM 6.2 clean instance and move our content to it with CRX2OAK tool for example.

So which variant is better (in place upgrade or new AEM 6.2) and why?

Thanks in advance!

Inplace upgrade is the recommended method of upgrading as this is the method that is heavily tested within Adobe. There are many tasks that are performed during an inlace upgrade that would not be performed if you were to use only crx2oak, for example a number of post upgrade tasks that are only run during an inlace upgrade. An example of such a task would be changes to the MSM/Livecopy, if you simply used crx2oak the content would not be updated to reflect the changes required for 6.2.

If you were to use crx2oak, then after your migration, you would need to run a full set of regression tests and then determine if the issue is a custom application issue or if it is caused by you not doing an inlace upgrade.

Here's a related thread on upgrade vs fresh install. Although it is specific to 6.1, it may be relevant here.

I think it depends on different variables. If you have a lot of content, starting from a new instance means that you need to upload all contents and asset and this task could take more than 2 day, so if your customer is not able to wait for more than 2 days this solution is not applicable.

Can you please provide link to related thread?

Thanks Antonio,
we looks at CRX2OAK tool and looks like it can move content quite quickly. But I am not sure about time for in place upgrade. Will it take less or more time
