Volker,

I have some questions, i have to perfom a migration (upgrade) from a 4.6C system to a ECC5 system. Probably the OS of the target system will also be changed (linux)

To my opinion I first have to upgrade from 4.6C to ECC5.0 and the do a heterogene systeem copy from ECC5.0 to ECC5.0 Correct me if I a wrong

Is it possible to upgrade directly from 4.6C tot ECC5.0. What SAP tools and pdf documents do I have to use

cheers

Richard

Hi Richard,

first of all I moved this new reply to a new topic as it has not too much to do with the old threat.

Then to your question:

To move from iSeries to Linux is a heterougenious systemcopy or called Migradtion as well. There the SAP release stays always the same. To do this migration, you need a special for this trained consultant with the migration certificate where are about 1000 worldwide do exist like me.

The upgrade from 4.6C to ECC 5 or 6 is in both cases a single step upgrade. But then the OS & DB stays the same.

=> You do have 2 steps in front of you.

As you might have an old iSeries and do not want to invest in iSeries any more, it might be advisable to buy a new, big & fast Linux server (where you have to select the DB of your choice too (DB2, MaxDB or Oracle)) first and then do the migration first.

On this new & fast hardware you then would do the upgrade to ECC 5 or 6.

You could do it vice versa as well, but the runtime will be a lot longer then.

Are you still on EBCDIC ?

If yes, it would be advisable to migrate first, as the upgrade on iSeries requires ASCII and this would mean one extra step, that would disappear with a first migration.

You should keep in mind in all these steps, that the OS & DB changes and you neednew skills !!!! Most customers do not have these new skills on the new platform - especially not with the large DB sizes of SAP databases like 300 GB ... => you need a good consultant of the target platform and need a lot of training for you and your basis collegues.

You see, that the idea of you (or your manager) is very interesting, but not totally easy. Therefore this would need some consultancy in my eyes ...
