Is SOA tooling update site for JBDS 5 compatible with JBDS 6?

Issue

• We are considering migration from JBDS 5 to 6, but found that it has no out-of-the-box support for SOA tooling nor "update site" patch available on the Red Hat Customer Portal as of December, 2012.
• Can we apply the patch jbdevstudio-soa-tooling-updatesite-5.0.1.v20121025-2155-H2-GA.zip to the newly released JBDS 6, or do we need to wait for a special SOA-P "updatesite" specially tailored for JBDS 6?
