AEM custom 6.3 bundles will work on AEM 6.4
Recently we have done AEM in place upgrade from AEM6.3 to AEM6.4. once the upgrade is completed with 6.3 custom code(built using the uber-jar.6.3) we observed that the 6.3 bundles are up and running in AEM6.4 without compiling and building with uner-jar6.4.
is it is the right behavior 6.3 bundle status is active in AEM6.4 environment? please suggest.
