Получил нетривиальный ответ от МС. Буду перечитывать вечерами

Issue Definition: Your client is having Axapta 3.0 SP5 with Swedish DIS layer and data in DIS- fields and tables and you need input regarding the best way to upgrade to AX 2009 with DIS stored data.
Please review the AX 2009 Upgrade Guide:

The easiest upgrade will be always from Ax 3.0 SP6, but it is
technically possible to go from AX 3.0 (any SP) to AX 2009, however:
1) If the LOS layer (cost accounting for example) is involved and you’re
upgrading from Ax 3.0 SP5 or earlier, you will need to test the upgrade and you
might have to program your own upgrade scripts, otherwise there is a risk of losing
the data. We would recommend to go from
3.0 SP6 if any LOS layer is involved.
2) If a country specific DIS layer is involved(any you’re upgrading from Ax 3.0
SP5 or earlier), you will need to go to at least from AX3.0 SP4 due to changes
between AX 3.0 SP3 and AX 3.0 SP4 DIS layer data model. Upgrading from directly
from AX 3.0 SP3 with for example PL
DIS layer will lead to a data loss. As in the point 2#, you can write your
own upgrade scripts (or migrate those from SP4 DIS) to prevent the data loss and to
be able to go directly from AX 3.0 SP3 to Ax 2009

Technical note: The reason why we recommend upgrading (to Ax 2009) from Ax 3.0 SP6
is that SP3 to SP4 (DIS,LOS) upgrade scripts are in SP6 (or SP4 etc), in LOS or DIS
layers. So if you go from SP3->SP6, upgrade scripts in ReleaseDBUpdate30SP*... will
take care of everything.

I hope this explains your query.
Scope Agreement: To get back with an answer regarding the best option to upgrade from AX 3.0 with DIS to AX 2009. Once this information is handed over this case would be considered as closed.
