Hi Prabakar,<br />it seems it&#39;s failing here:<a href="https://github.com/liferay/liferay-portal/blob/7.1.x/portal-kernel/src/com/liferay/portal/kernel/portlet/bridges/mvc/MVCPortlet.java#L281">https://github.com/liferay/liferay-portal/blob/7.1.x/portal-kernel/src/com/liferay/portal/kernel/portlet/bridges/mvc/MVCPortlet.java#L281</a><br /><br />because _renderMVCCommandCache has been initialized, maybe the init method hasn&#39;t been called, can you verify why in this case the init method is not called?<br />Cheers.

We are migrating from Liferay 6.1 to 7.1. After migration, we are getting &#34;Portlet is temporarily unavailable&#34;.
