AEM Upgrade to AEM 6.5

Adobe documentation captures all the scenarios for the AEM upgrade^[1]. On a high level, the changes are:

There are two ways to upgrading the AEM instance, one is in-place upgrade and other is fresh install approach based on AEM content size.
Upgrade artifacts by compiling against 6.5 uber jar.
Test and fix any issues due to deprecated features/overlaid capabilities change.
From 6.4, as part of the sustainable upgrades process, there is a repository restructuring that can be done (not mandatory)^[2].
Process on how to roll out the changes to production.

If this is hard, adobe offers a backward compatibility mode from 6.3 with which one can run a 6.3 AEM artifact on a 6.5 instance^[3].

Pattern detector is a mechanism provided by Adobe to easy identification of possible problems that will come up during upgrade by validating against deprecated features and overlays^[4].

AEM 6.5 is compatible with Java 8^[5].

No Java virtual machine was found

Error: A Java runtime environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\Program Files\Java\jre1.8.0_221\bin

Cause of error: when we update the Java version, or install a new version of Java in machine.

Solution: We need to manually update path of current JRE or JDK path in Eclipse setting file.

Where I can find the Eclipse setting file?

Directory: C:\Users\rashidjorvee\eclipse\jee-2019-06\eclipse\eclipse.ini
Below is the sample of eclipse.ini file. You may open this file using notepad and notepad++.

-startup
plugins/org.eclipse.equinox.launcher_1.5.400.v20190515-0925.jar
--launcher.library
C:\Users\username\.p2\pool\plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.1000.v2019882098-2010

-Doomph.redirection.index.redirection=index:/->http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/

In eclipse.ini file please update the correct JRE or JDK path at line number 13 under the -vm (virtual machine) and then save the file.

This will fix your issue and you will be now able to open the eclipse IDE without any issue.

Where to find the installed JDK and JRE in machine?

In windows inside the profile files >> Java, you will find the installed JRE and JDK.

e.g. path of a JDK version 1.8 : C:\Program Files\Java\jdk1.8.0_221\bin
