My understanding is this. If you have a legacy wiki that already has Forum enabled, you can request that Discussions be enabled. Since the conversion script has not yet been updated for all of Discussions' new features, Forum should be left active. However, you may want to explicitly request that just to be safe.

However, the co-existence of the two features is only until the conversion script is updated. When it is, new requests will not be permitted to keep Forum. Any legacy wiki that still has Forum (either with or without Discussions) will lose it when the wiki is migrated to UCP.
