UPGRADE classic GL to New GL

Hi Gurus,

our client wants to upgrade SAP from 4.7 to ECC 6.0 with NEW GL functionlality, could anyone please explain,

1) the things I need to take care of during the initial phase of Project ,

2) Is there any step by step procedure to folllow,

3) The reports which we have in SPL (which we don't want SPL in ECC6.0 and required all the reports to be transferred to New GL, is there any automated way ? or do I need to create all the reports from Scratch? )

Regards,

Sandhya
