Upgrade Projects can follow one of the 2 possiblity.
1. Technical Upgrade: in which the basis consultant will handle the same & transport the configurations & developments from 5.0 to 6.0. Subsequent to which functional consultant & Abaper will do the necessary change in configuration or further configuration & Abapers will do necessary developments required.
2. Traditional ASAP methology: which would refer as new inplementation as a whole.

HI
Major difference is ECC6 is netwear product having WASJAVA+ABAP
secondly support Unicode apart from this we have other diff. you can get from master guide from service.sap.com/instguides
For installing ECC 6.0 you required a solution manager key.With out solution manager key you cannot install ECC6.0.
For ECC 6.0 is called netweaver component here you have ABAP+JAVA stack.
ECC6.0 supports UNCODE.
For installing 4.6 you don't required solution manager key.It only having ABAP stack.
4.6C supports NONUNICODE.

Dear Madhan,
STEPS IN TECHNICAL UPGRADE
Basis Team will do the prepare activities. (UNIX, BASIS, DBA).
Developer need to run the Transaction SPDD which provides the details of SAP Standard Dictionary objects that have been modified by the client. Users need to take a decision to keep the changes or revert back to the SAP Standard Structure. More often decision is to keep the change. This is mandatory activity in upgrade and avoids data loses in new system.
After completing SPDD transaction, we need to run SPAU Transaction to get the list of Standard SAP programs that have been modified. This activity can be done in phases even after the upgrade. Generally this will be done in same go so that your testing results are consistent and have more confident in upgrade.
Run SPUMG Transaction for Unicode Conversion in non-Unicode system. SPUM4 in 4.6c.
Then we need to move Z/Y Objects. Need to do Extended programming check, SQL trace, Unit testing, Integration testing, Final testing, Regression Testing, Acceptance Testing etc.,
The main Category of Objects that needs to be Upgraded is
Includes
Function Groups / Function Modules
Programs / Reports
OSS Notes
SAP Repository Objects
SAP Data Dictionary Objects
Domains, Data Elements
Tables, Structures and Views
Module Pools, Sub Routine pools
BDC Programs
Print Programs
SAP Scripts, Screens
User Exits
