TAXINJ tax codes in TAXINN

Hello,

We are working on Tax procedure conversion from TAXINJ to TAXINN.

Due to some valid reasons, business has decided as they want to use condition record as tax classification. It means that, what are the active tax codes available in TAXINJ , the same we need to create in TAXINN.

Assume that, there are 100 active tax codes are found in TAXINJ.

Here i am feeling as rather than creating new two digit tax code, shall i create that 100 active tax codes with the same name in TAXINN...?

TAXINJ active tax codes. e.g:N1,N2...

so, we want to create in Taxinn also N1,N2... ,  because of this approach,

1.Since users are familiar with the tax codes, the same they can use after migrating to Taxinn.

2.No change in the tax code wise account determination (OB40)

3.Tax code mapping will be easy for the migration data/program.

Could you please share your experiences on this approach..?

Thanks,
