MDM 7.1 - Migration Server

[former_member199849]

Hi friends!!

I have a SAP Netweaver MDM 7.1 installed on Windows 2003, we are going to change the server to Windows 2008, I don't know if the migration will be a new installation and then migrate the database, if this is the case, how is the correct procedure to migrate database, repositories? Do you have a useful guide?
I am new in MDM.

Thanks

With Backup and restore? , because I going to install the new MDM with the same caracterisitc, SID, ports, etccc so I guess backup and restore will be an option, my DB is SQL 2005

Am I rigth?

Hi,

no I do it without Backup and Restore.

When you have installed a new system you must now make an archive with the MDM Console from every repository. Than copy it to the new server unter (on linux it is under /usr/sap/<SID>/MDSxx/mdm/archives) and do an unarchive on the new server.

Before you make the unarchive you must to create an repository. Logon to the repository and than unarchive. You will automatic logoff from the repository, but that is okay.

You should also edit the *.ini files if you have some spezial parameter in the old system.

Hi,

with archive and unarchive with the mdm console it is easy. The files from the repositories after the archive was at my system not so big.

(my old system landscape was sun os / oracle. the new one is linux / oracle)

My prerequisites as SAP Admin was only to copy the global part from the mds.ini, mdis.ini and mdss.ini to the new server.

For my it was important that the new MDM System must have the same MDM version like the old MDM System.

At our system it was all. There was also no problem with the repositories after the import. My luck was that my customer want not change the database.

About the size of the BD? for doing this method: archive and unarchive, are there limits with BD size?

Hello,

Issue's can be any depending on the environment you are working with.

The repository gets corrupted, sometimes the maps are imported, validation needs to be written again

Generally if you follow the document, chances of encountering and error is minimum.

Are there prerrequisites, issues that I have to consider?

[thomas_haase]

Hi,

I do it the last weeks from SunOs to Linux.

My way was to install a new MDM system (MDM and DB)  with the same versions on the new server. Make an archive from the repositories(MDM Console), transfer it to the new server and make an unarchive (MDM Console) on the new MDM System. (since an SAP note is this way the only supportet way)

The MDM Configfile (mds.ini, mdis.ini, mdss.ini) should the same like the old ini files.

The repostory part I dont copy to the new ini's file. only the global part.

After this my mdm was running without any problems.

I hope it helps.

Greeting

Hi Thomas

How do you copy the repository? Do you have a guide?

[Former Member]

Hi,

To copy a repository, use Archive and unacrchive commands. Procedure in brief-

log into MDM console -> mount the Source MDM Server -> Archive the desired repository

-> copy the .a2a files(archive fails) from /usr/sap/<SID>/MDS**/mdm\archives and paste it at the same loction of target system

->mount the target server ->unarchive the repository

Please refer to Part 6 of the below Reference Guide.
