In place upgrade or new env build with 5.6.1 -> 6.2


Level 5

HI Team ,

We are looking at upgrading from 5.6.1 to 6.2.

I have seen Authentication service support missing error while upgrading from 5.6.1 to 6.0 earlier.I see couple of more projects who have chosen to build new environment altogether instead of in place upgrade.

What would be good approach in my case ?

we have close to 160 components(mostly custom not overlaid from libs)

5200 pages approximately.

Thanks Tuhin,

Have gone through this link.

But this link assumes that you want to go for in place upgrade and illustrates the same with crxtooak utility etc etc.

I am interested in finding out if we can take a new 6.2 instance make it up and running and then move the code,content, data systematically.

This way it wont require upgrade of existing repository.




if you don't want to use the in place upgrade, then you could use crx2oak to migrate the content to a clean AEM 6.2 repository. Then the responsibility of updating the codebase, workflows etc would entirely be your responsibility. There are a number of tasks run during the upgrade that would not be run when only migrating the content to a clean system.The crx2oak tool can be used to migrate content. The actual upgrade process is two steps, upgrading the content, then upgrading the repository by running the 6.2 jar.

Support probably have a lot more experience with inlace upgrades. 






the recommendation is to do an inlace upgrade, as this not only upgrades the repository but also runs post upgrade tasks which would not otherwise be run. Orphaned versions can only be migrated with an inlace upgrade.

Apart from the link above, there is a good section on planning your upgrade[0]

There is a dialog conversion tool you could use as a starting point[1]

There are also plenty of threads and inline blogs about upgrading[2]

So the best course of action is to read as much as possible to best prepare for your upgrade.
