Hi,

We recently upgraded from Liferay 6(L6 - version 6.0.6) to Liferay 7(L7). The migration was partial, in the sense that 50% of the applications were moved from L6 to L7. The remaining portlets are part of phase 2 of migration. We are in a situation where in we want to redirect certain portlets from L7 to L6-which is on a different machine. We tried redirecting from L7 to L6 using Apache on top of Liferay through Rewrite rules. However, Apache instead of redirecting to L6, redirects back to local L7. This apache server is configured on the machine hosting L7.
Is there a way of redirecting portlets from L7 to L6? Is Apache redirection the proper way to go about it? Or is there some alternative to this. We have been stuck on this redirection issue since two weeks without any success.
The following is the virtual host configuration in Apache:

*x.x.x.x = IP of machine hosting L7*
*y.y.y.y = IP of machine hosting L6*

<VirtualHost *:80>
ServerName x.x.x.x
ProxyPreserveHost On
RewriteEngine On

#Rule to redirect xyz portlet from L7 to xyz portlet on L6
RewriteRule ^/?group/abc/xyz(.*) http://y.y.y.y:9000/group/abc/xyz$1 [P]
ProxyPassReverse /group/abc/xyz/ http://y.y.y.y:9000/group/abc/xyz/

ProxyPass / http://x.x.x.x:8080/ #To redirect default requests to liferay tomcat(L7)
ProxyPassReverse / http://x.x.x.x:8080/
</VirtualHost>

Are we missing out something in the above Apache virtualhost configuration? Or does Liferay not allow internal private portlets to be redirected to Liferay hosted on different machine. Also, we are using CAS for login on both L7 and L6.
