Some of the differences ABAP Module side:

For installing ECC 6.0 you required a solution manager key. With out solution manager key you cannot install ECC6.0.

ECC 6.0 is called net weaver component here you have ABAP+JAVA stack & for installing 4.6 you don’t require solution manager key. It only having ABAP stack.

ECC6.0 supports UNCODE & 4.6C supports NONUNICODE.

Major difference is ECC6 is net weaver 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.

In terms of ABAP some function modules are obsolete in 4.7. e.g. WS_UPLOAD, WS_DOWNLOAD etc. You can find the list of obsolete FMs in the table RODIR. These need to be replaced in the ECC System.

Also ECC is very strict in case of EPC Errors. You need to check the EPC and remove the call function interface errors where it says SLIN observes catching of a runtime error. These might work with no issues in 4.7 but will short dump in ECC.

If you are doing to a Unicode conversion also. You need to check the transaction UCCHECK for Unicode errors. You also need to replace obsolete statements like >< and => , =< etc.

If you want to know more ABAP changes go to transaction ABAPDOCU and there is a node ABAP Changes by Release. You can see more ABAP Changes version by version here.
