<div style="direction:ltr;font-family:Tahoma;font-size:10pt">Yes, hence the need to support the v2 resources as seperate things. Then I can rewrite the templates to include the new resources rather then the old resources as appropriate. IE,
 it will be a porting effort to rewrite them. Then do a heat update on the stack to migrate it from lbv1 to lbv2. Since they are different resources, it should create the new and delete the old.<br>

There needs to be a way to have both v1 and v2 supported in one engine....<br>

<br>
Well I'd hate to have the V2 postfix on it because V1 will be deprecated<br>
and removed, which means the V2 being there would be lame.  Is there any<br>
kind of precedent set for for how to handle this?<br>
<br>
Thanks,<br>
