upgrade from Microsoft Dynamics NAV PL 5.00 SP1 to Microsoft Dynamics NAV PL 5.00 SP1 FP1


I’m trying to do an update Microsoft Dynamics NAV 5.0 SP1 to FP1. In the document:Upgrade Toolkit for Microsoft Dynamics NAV 5.00 SP1 PL FP1 read:
To upgrade the customer’s database Implement Step 1: Preparations Datafrom Microsoft Dynamics NAV Upgrade Toolkit documentations (Task 1 -Task 7).
I understand that these words refer to some other document, where are thechapters 1-7?
Maybe someone has experience with thisupgrade?

Follow the instructions for Microsoft but I think I came to the wall. I con not run the Delete function - Unused Old Tables on the forms 104,002Upgrade - New Version Codeunit 104003 or run the Delete Old Tables.

Delete option in this dialog is disabled.

I will be grateful for any help, maybe there is some Polish user, who couldhelp me? I will take a paid cooperation.
