Separate ASCS and PAS from Database server

[former_member220499]

Dear friends, in a customer we have the following need:

We need to separate de ASCS and the Primary application server to a host different from database server. The SAP system is an ERP 6.0 EHP4 based in NW 7.01.

We have used Software provisoning manager to splitt off the ASCS from the CI. Before the splitt off we only had the directory DVEBMSG00, and after the splitt off, we had ASCS01 and DVEBMSG00 directories. But, this is only half of the solution, because we need to move this services to another hosts.

We tried to use Software provisioning manager to deinstall the ASCS, and install it in the other host. This works. But the problem is the Primary application server, because if we uninstall it, when insttall in the other host with the option "System Copy" the sapinst promts for the installation export.

In the Marketplace i could not find any note form aour scenario.

Do you know a way to separate de CI and the PAS from de database server without a system copy?

Thanks and best regards.

Hi friends. We did the separation succesfuly for an ERP system 6.0 with EHP4. Instead of the documentation we used the Software Provisioning Manager (SWPM) for > NW 7.1 (The ERP sistem is based in NW 7.02). Finally, we uninstalled the ERP (Only the primary application server and not the database) and installed in the new machines with the same software provisioning manager (ASCS + PAS). Why we did not use the 70SWPM? Becasue in the installation of the PAS (Primary application server) it prompts for the migration export. But the SWPM not prompts for the migration export coneccting directly to the database server.

I hope this will be usefull for anyone else.

Thanks and best regards.

Hi

But if you have a system based on SAP NetWeaver 7.0x, this option is not available in the 70SWPM, The only way to do that would be running a system copy of the system. Then during the target system installation, you would be able to install the new system with sepated ASCS from PAS . "
