Upgrade 5.1 to 2009

Hello,

I have a Nav 5.1 in production, and i want to (for now) migrate to 2009 R2.

The conversion for the classic client is ok. Everything works perferctly.
The next step is to progressly migrate with RTC.

How can i import the 2009 objects on my installation. I don't want to loose the specific fields, codeunits .. I understand i have to recretate all the reports and the pages, but i want to keep the cronus one for begining.

so i want my old 5.1 datas (tables + codeunits + dataport) and the new 2009 datas (pages, reports, updated codeunits, updated tables)

is it possible ?

is there is a merge tools ?

Thanks.

Tiam.
