Can I repeat a UNICODE CONVERSION Export more than once?

We are about to embark on a project to move all 3 sap systems to new hardware.

On the way we plan to perform a Unicode conversion.

We are also including a refresh of our DEV and TST environments from PRD.

So the 3 phases of the project are:

• 1.Export PRD-> UNICODE CONVERSION -> IMPORT DEV
• 2.Export PRD-> UNICODE CONVERSION -> IMPORT TST
• 3.Export PRD-> UNICODE CONVERSION -> IMPORT PRD

Our system is small and we often refresh DEV and TST from PRD.

The issue I am concerned about is that there are some steps in the preparation for the UNICODE export that look like they delete data/build nametabs that may disrupt the continued use of PRD.

The guide I am using is titled “Single Code Page System Conversion to Unicode NW AS 7.0 EhP2 :

I had planned to do the following :

• 1.Log all users off PRD
• 2.Perform the final perparation steps
• 3.Export PRD
• 4.Re-open PRD for usage.
• 5.Import the PRD Export into our DEV system

Will the steps in 2. Enable PRD to subsequently be used as a non-unicode system until the final export ?
