Newbie -Help Appreciated in setting up job

Hello,

I am very new to Kettle and would like to ask for help in setting up a job/transformation with teh following capability:
1. Check Database table to see if any rows currently exists
2. If rows exists, move the data to a backup table and clear current table
3. Read excel file
4. Store excel file into table that was cleared
5. Done

My problem has been with the parallel execution of the transformation. I have tried flow control but guess i am not doing correctly.
What is the best way of performing these actions?

Thanks
