ICNV Phase during SAP ERP Upgrade

Hello All,

We are doing an Upgrade of our r/3 system from 4.7 to ERP EHP6. Currently the upgrade of Production system is in progress. We are in the Preprocessing phase of the Upgrade where the ICNV is running.

The concern here is :

In the upgrade of Pre-Production system, the ICNV determined 5 tables for conversion whereas in the Production system only 3 tables. The two tables ignored in the Production are big tables (size approx 5GB) and have around 31million entries. The other 3 tables are not as big as these tables. My question is :

Q> How does system ( ICNV program ) determines the tables to be converted? What is the criterion? Can we include tables for the conversion?

Also my concern is that as these 2 big tables are not converted in ICNV, is there a chance of increased Downtime??

Please advise ASAP.
