Hi Experts,

What is the steps for me to upgrade SAPB1 from 2005A PL50 to 2007A PL46?

Is it my below steps?

1. Backup common database

2. Backup production database

3. Removal of B1 2005A completely including the addon, server tools

4. Install B1 2007A including license import

5. Open B1 2007A client and the B1 will ask you to backup before upgrade.

6. Install B1 client

Thanks.
