I wouldn't think so, the route was launched in build 4.9 to take advantage of the advancements in SP4. Won't be long to wait and you can always update to SP4 beta now. If you have the space for it, make another install so you don't affect your current build.

Thanks Graeme,
Unfortunately, at 860Gb, TRS19 is not something I have the luxury of just casually backing up "just-in-case" a beta update breaks stuff. (and that doesn't include the non-platinum TRS19 or TANE databases that I already have just "lying around" as well).
I'll just have to be patient.
Cheers,
Piere.
