Support Package Upgrade on SAP IDES 6.0 ERP 6

Hello,

Please, has anyone been able to apply any support package to SAP ERP 6.0 EHP6 IDES?

I have been trying to do that...but the phase IMPORT_PROPER is taking a long time.

Some people say it is not possible to apply support package to SAP IDES system....but I know it is possible as I have an SAP IDES ERP 6.04 that I normally apply support package on.

Any idea will be appreciated.
