Can we directly upgrade SAP ECC6.0 EHP-00 to EHP-06

Hello Experts,

Our current system is ECC 600(EHP00) with the following details

Processer – Intel(R) Xeon (R) CPU E5410 @ 2.33 GHZ

RAM        – 4 GB

OS          – Windows Server 2003 R/2 64 Bit

DB          – SQL Server 2005 Service Pack 2

We need to upgrade it to ECC606 i.e., to the EHP06 to get SAP BOBJ integrated.

Can any one please let me know if we can directly upgrade the system to EHP06 from EHP00 with the help of SOLMAN and KERNAL or we need to upgrade each EHP i.e, EHP1 --> EHP2 --> EHP3 --> EHP4 --> EHP5 and then to EHP6.

If we can directly upgrade to EHP06, please share the upgradation process or documents if any.

Thanks in advace.

Regards,

Satheesh Rachapalli
