Upgrade to AEM 6.0 from CQ 5.4

Hi All,

A very Good Morning.

I just wanted to know whether In-Place upgrade from CQ 5.4 to AEM 6.0 directly is possible? I searched many documents in Adobe sites. But all i could get is an upgrade process from CQ 5.4 to CQ 5.5 or from CQ 5.4 to AEM 5.6/5.6.1 or from AEM 5.6 to AEM 6.0. not a direct upgrade process from CQ 5.4 to AEM 6.0.

I referred below link to upgrade our current CQ 5.4 application to AEM 6.0. The below link provides an upgrade process to AEM 5.6.1 from CQ 5.4.

https://docs.adobe.com/docs/en/cq/5-6-1/deploying/upgrading.html

I tried the different ways and are listed below.

1. New installation of AEM 6.0 war into the Application server - working fine

2. Stand alone installation of AEM 6.0 jar - working fine

3. Application server upgrade using AEM 6.0 quickstart war - Not working

All the above mentioned ways are working fine except the last approach. The upgrade was not successful for the third approach. The crx-quickstart  folder of CQ 5.4 in domain is not archieved; the quickstart folder structure remains as 5.4 and does not hold the folder structure of AEM 6.0. The one issue that i could notice is that the sling.properties generated for the approach 1 and 3 are different. Why is it so? Whether the upgrade to AEM 6.0 is never possible from CQ 5.4 directly?

Anyone could please clarify whether the In-place upgrade in application server is possible or not from CQ 5.4 to AEM 6.0. Thanks in advance.
