upgrade to 2007a SP01 patch 7 to sp01 patch 09

Hi,

i see later in this portal this comunication:

'Unlike specified in the PatchReadme file of PL09, customers who are running versions previous to SAP Business One 2007 A SP01 must first upgrade to version 2007 A SP01 PL08 before applying 2007 A SP01 PL09 or higher'.

i've upgrade directly from Sp01 2007A patch 07 to Sp01 2007A patch 09

whic problem can i meet???
