You're on track Barb.

Suggestions:
!) Perform a full database backup

        (Hot or Cold - Must be a good backup)

2) Export full database, ensure no errors are reported.
3)  Backup export file (ensure it is a good copy)
4)  Produce a 'Create database' script by:
	alter database backup controlfile to trace;
 	modifiy the trace file create in the udump directory to 
	   include the 'create database' syntax
5) modify your init.ora file and specify DB_BLOCK_SIZE=4096
6) Run script
7) Import the full export file.

This is a rough plan and I am encouraging to review all details applicable to your endeavor and most importantly....Test before implementing and be certain you can go back if necessary !!!

Good Luck,

-D
