Inhouse ERP to Cloud ERP - Data Migration

We are moving from a inhouse ERP to Cloud Service ERP. What would be involved in the following steps:

-Extraction, Concolidation and Cleansing of Data to be migrated (When is the data cleaned)

-test loads

-production loads

The cloud base service wants this data in CSV format..

 We have been given excel templates to have data imported into.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Using Excel as middleware for a data migration project?  Welcome to 1997.  Just kidding... you have no choice.

What RDBMS is the data coming out of and what's it going into?  I presume it's an RDBMS.  If it's like Oracle to Oracle, for example, the process will be less complicated.  If it's Oracle to DB2 it'll be more difficult.

You have data consolidation and cleansing steps... if you're not doing a forklift migration the verification and validation is going to have to be _extensive_ and it's going to be difficult to do a before and after reconciliation.

What categories of data elements need cleansing?  Name and address, codes and indicators, financial data?

If Excel is your only ETL tool (Extraction/Transformation/Load) - E and T mostly, not so much L of course - you'd need someone who's really really good with Excel.  I'm talking about knowing stuff like Vlookup(), Exact(), and Index() like the back of her hand.  It'd be even better if the person can ride macros and VBA with ease.  Otherwise it'd be a very manual and slow process, frustrating everyone.
