Question about Time finder Mirro with metas

Hi

Let me tell you about my production environment

I have 48 (8.43Gb) standard Devs and I created 6 (8-way) metas with those devs, 67GB each , I mean, i have assigned those metas to my production server .

I have also 48 (8.43Gb) BCV devs to create a mirror between the 48 standard and these BCVs, but for my BCV's I did not create metas, those are 8.43Gb

The question here is:

do i need to create 6 bcvs meta similar to my production environment in order to ESTABLISH a mirror between them?

or

Can i use the 8.43GB BCV to ESTABLISH a mirror between them? i mean, ESTABLISH the BCV no mater the standard is meta and the BCV is not?

Same case for SRDF?

Regards
