Microsoft Strategy for Report Builder

Hi,

I wanted to ask about the future of Report Builder 1.0. As newer versions are released of Report Builder (now with 3.0), I was wondering – does this mean I need to re-create my report models in RB 3.0? I know RB 1.0 is still supported within RB 3.0 – but is this for a limited time? Do I need to consider a discontinuation of RB 1.0 in the future or should I continue developing RB 1.0 models and they will be run against RB 3.0?

I would really appreciate an official answer.

With thanks in advance,

Ella
