ACCS Migration 6.4 to 7.0

[IPOCraft]

Hi there:

Somebody have an experience in this kind of migration or a more clear document? The Avaya documents says something like: "Due to changes made in ACCS 7.0 release regarding improved security stance, migration of the ACCS 6.4 certificate store to ACCS 7.0 or higner is not possible" and then somethign like "migrating security custom security certificates has caveats that require planning consideration before beging the process" and nothing more.

Thanks...
