[Help] Move ECC system from one server to another - Considerations

[martin_simois]

Hi Guys

We currently have two SAP ECC 5.0 Instances over DB2 9.7/AIX 6.1 on a same server (WS01), and now we are splitting this, by leaving Development box on WS01 and moving QA to WS08

What would you think/recommend the best approach to fulfill this requirement

Im taking in mind such things like, transport system, RFC connections, Database and SAP Profiles

What steps would you think are mandatory to have QA system fully working on a brand new server

Is an option to install an system from scratch on that new server (WS08), and they restore the actual database and perform the post processing steps just like a refresh, and then adding that system to the actual ECC landscape

Best Regards

Martin

This process is called "system copy".

It's an option but not necessary to first install a full featured system and then "overwrite" the database.

You can install a new system using the database backup of the original system.

Hi Markus.

Yes, its a systemcopy, but my question is mainly in what is the best option to move the SAP instance from one to another server reducing downtime.

By moving the filesystems from one to another server. I dont think is an option due DB, SAP parameters and other configurations, besides servers name and IP would be different.

I have two approachs to accomplish this.

1. As Markus mentioned, performing a system copy,

Is there a SAP guide for ECC 5.0 or NW 7.0 ABAP Guide will be sufficient?

2. Creating a new system as a clone of the actual QA system, and mirroring DBs. At some point, switch over and apply the latest logs. It should take less downtime

Thanks!
