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.
Thanks,
Kevin

But I think, V2 has introduced some new components and whole association of the resources with each other is changed, we should be still able to do what Kevin has mentioned ?
Thanks

There needs to be a way to have both v1 and v2 supported in one engine....
Say I have templates that use v1 already in existence (I do), and I want to be able to heat stack update on them one at a time to v2. This will replace the v1 lb with v2, migrating the floating ip from the v1 lb to the v2 one. This gives a smoothish upgrade path.
Thanks,
Kevin

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