Sap Server movement from physical to virtual(p2v)

Hi all,
We currently have two older versions of R/3 running 4.6c and 4.7ee, both IDES versions.
These versions have been out of support for some time.
We have these instances running for reference purposes. We have new versions of R/3 ECC 5.0, 6.0
also running in our company. All these versions of R/3 are IDES.
Our Windows administrators are of the opinion that servers on which the instances 4.6c and 4.7ee are running are very old,
and spares are hard to find. So they want to move these instances from a physical environment to a virtual environment.
I have read through the Note: 1409608.
It says,
SAP does not support SAP systems that are installed on Windows 32-bit
in a virtualized environment. If you plan to migrate your SAP system that is running
on native hardware on Windows 32-bit to a virtualized environment
on Windows 64-bit, it might be necessary to upgrade the SAP system to a higher release.
For these configurations, SAP recommends to migrate the SAP system to Windows x64 first
and then upgrade the SAP system.
Now, I don't think is it quite possible to upgrade 4.6c and 4.7ee to 64 bit.
License keys on windows are based on SID, Hostname, MAC address of the network card.
If we make sure that the MAC address is the same and
that its at the same place as before(sequence of multiple network cards is the same),
we can still Use the old license.
Our Windows guys say its very hard to retain the MAC address, they can try it.
So with these old versions of R/3, how can we keep them running, if they have to be moved from Physical to virtual,
as license keys and installation software is hard to get.
Regards,
Vishnu.

Hi Markus,
Thanks for your reply. Would open an OSS call.
I have looked at the note mentioned by you, and since our OS is windows, I thought the below statement
holds good in my case. From the note I have also deduced that for Windows, licenses are based only on the Hardware Key.
Am I wrong in assuming this?
Only Windows uses a hardware key that does NOT depend on the hardware.
A new installation of Windows definitely causes the hardware key to change.
I have also looked at note 793649, which says Hardware key changes only when,
1. Formatting the machine and reinstalling Windows.
2. When changing the computer name.
3. When changing the domain (it will not change back when returning to the previous domain).
Regards,
Vishnu.

SAP Server Movement from one Location to another Location

Dear all,
We plan to move SAP servers from excisting location to new location .
Is there any precaution to do before shifting SAP Servers .
Regards

Hi,
How are you doing the migration, are you still connecting to the disk sub system ?
If you have a DR plan off site? good idea to go over that plan, that will help
Just a few things to think about, though some may not matter as I do not know you complete plan.
startup Profile changes
Background jobs that have hardcoded with previous hostname
Operation modes
external interfaces
Logical paths transaction (file)

Conversion from physical to virtual server

Our server technology group wants to convert our physical
server that contains the RoboEngine to a virtual server (using ESX
VMware). We are using RoboHelp 5 to publish WebHelp to the
RoboEngine. Has anyone else converted from a physical to a virtual
server? If so, could you tell me about any problems you
encountered?
Thanks,
Liz

Hello Nelson,
There are quite lot of things in TMG which are dependent on Hardware.
If you want to migrate from physical to virtual server, you can follow the steps here which are recommended/supported way of doing it.
Though this article is for ISA to TMG migration, still you can follow the same steps for Physcial to Virtual migration.

Please let us know, how it goes!

SCCM 2012 hierarchy from Physical to Virtual

I have an existing standalone SCCM 2012 hierarchy on a physical server with ~ 50K clients reporting with additional servers hosting various site system roles. Now the requirement is to migrate this hierarchy on a virtual environment. Client doesn't want
to do P2V migration and wanted to have the migration done on new infra.
In current hierarchy we have client health compliance at ~90% and we have to maintain the same post migration additionally there are lot of collections, packages and deployments those needs to be successfully migrated.
Please suggest a feasible and most efficient solution for this

Client doesn't want to do P2V migration
Assuming that you have done your homework and are OK that Virtual is the way to go, the easiest way to migrate from Physical to Virtual is to carry out a P2V migration. I don't quite understand this.

Move Exchange 2010 SP2 from Physical to Virtual

I am currently running Exchange 2010 on a server which is hugely underutilised so am hoping to virtualize Exchange and other servers on this machine.
What is the best way to move/convert Exchange?
I will require this machine to be reinstalled with Server 2008 R2 server core to run only Hyper-V.
I thought of backing up (to multiple locations, just in case!!), reinstalling the server with core + Hyper-V, then restoring the backup to a new VM.
Or should I use the Sysinternals Disk2vhd tool first. Convert to VHD, then reinstall server with core and add the VHD as a new VM?
The Exchange databases and logs are on a separate RAID 5 array which would be left untouched so would making this disk available to the Exchange VM would allow it to continue where it left off after the server was restored from backup to the new VM?
I also read it is not recommended to use P2V tools with Exchange, but since I am required to reinstall the machine what choice do I have? In that case should I install Exchange on another server, move all databases and users to that server, reinstall old server,
install Exchange VM, then move all databases and users onto the new VM?
The more I think about this, the more my head spins, so any insight is appreciated.
Thanks.

SAP ECC Migration from Physical to ESX

Dear All,
My company is moving from Physical Servers to Virtual Platform (Vmware ESX). We are using 7.2 kernel on RHEL 5.3 64 bit for SAP HCM. My plan is;
1) Shutdown all services
2) Clone Physical Server into VM using vCenter Converter
3) change all DNS Base information and update IP address
4) Restart the services on new server with new IP Address
My take is i need to request new License for new Hardware. Please suggest me what else i need to consider during this process.
Thanks.

Hi,
My take is i need to request new License for new Hardware
Yes you need to request for new license since your hardware is changing.
Apart from the steps mentioned by you,
1) You need to readjust the RFCs
2) Adjust the TMS configuration
3) Adjust the SAPlogon pad entries for endusers.

Blue Screen Error during starting Windows Server 2008 R2 (VM on Hyper-v WinSvr2012) Using a Physical to Virtual (P2V) VHDX.

Hi There,
I'm trying to migrate one of my physical Windows Server 2008 R2 to Virtual Environment (Hyper-V on WinSvr2012).
(The original physical machine had multiple partitions on the windows HDD and 2 other boot able OSs where installed on 2 of those partitions ...) So anyhow, After heaps of trouble shooting and fixing the boot records, it finally started booting the
Windows but when it got to loading C:\windows\System32\Drivers\Classpnp.sys
and it crashed, a blue screen poped up saying "A Problem has been detected and windows has shut down to prevent damage to your computer ... ) and then system got rebooted automatically.
I have tried chkdsk, also tried copying a new classpnp.sys to replace the old one but no hope. I don't think is not a damage file issue. Not sure, but it is probably related to changing the HDD devices or SCSI/IDE controllers?
Any idea?

1. You have placed your problem in wrong forum. Address your problem to Server forum instead.
2. I do not think it is liable configuration. I have not heard about migration of multiboot HDD. Try to split it. Pay attention to better preparation. I would expect separate target VM.

Moving CUPS from Physical to Virtual

I am trying to move my CUPS server from a physical server to a virtual server. I am running CUPS 8.5.3 (8.5.3.10000-60). I have followed the same steps as doing the migration for Call Manager. Backed up server to the network, installed fresh copy and restored the backup. It goes through the restore and is successful on everything but the DB. When I look at the log it has the following:
----> BEGIN Standard Error
bad decrypt
12406:error:06065064:digital envelope routines:EVP_DecryptFinal:bad decrypt:evp_enc.c:438:
Any suggestions would be great.

Exchange Server 2010 - DAG - Physical and Virtual

Hi All,
we are trying to configure Exchange Server 2010 SP1 DAG with TWO Servers, we are getting the error sector size on log file header was mismatch
1) Physical Server - when we check the sector size on log file - 512 bytes   (RAID5)
2) Virtual Server - when we check the sector size on log file - 4096 bytes
is there any workaround to solve this issue or do i need to re-install the physical server with 4096 sector size..
When i check the Volume details on both machine
1)
Bytes Per Sector :               512
Bytes Per Physical Sector :       <Not Supported>
Bytes Per Cluster :               4096
Bytes Per FileRecord Segment    : 1024
2)
Bytes Per Sector :               512
Bytes Per Physical Sector : 4096
Bytes Per Cluster :               4096

Hi Jared,
I've got a question regarding your answer.
We have an existing Exchange 2010 DAG configuration with 3 mailbox servers in NL and 3 in the UK.
2 for normal databases at each site and 1 for Archive databases at each site.
The current Mailbox servers for the Archive databases are Hyper V 2008 R2 based VM's with a passthrough for storing the databases.
We now want add 1 new Mailbox server for storing archive databases at each site and add them to the DAG.
Can we use Windows 2012 Hyper-V hosts and create the new VM's with 4k sectorsize vhdx files for the new mailbox servers ?
Regards

SAP Server upgrade from Windows 2003 and 2008 R2 with Oracle Database

Hi,
We need to upgrade upgrade our Windows servers that are running our SAP systems from Windows Server 2003 to Windows Server 2008 R2. We are using Microsoft Clustering for HA so an inplace upgrade seems not possible.
Someone has suggested to us that we will need to export our database and reimport it to achieve this upgrade however but I cannot understand why this would be necessary (we are not changing the underlying filesystem!).
Could someone please confirm whether a database export and import is required for this OS upgrade scenario? I have done a bit of research but nothing has jumped out and now I need an answer to this quickly.
We are running
- ERP 6.0 NW 7.01 (soon to be 7.02 with ABAP stack only)
- XI(PI) Java & ABAP
- SRM (Java & ABAP)
- Portal (Java only)
- PLM (Java & ABAP)
- BW (BI 7.0) (Java and ABAP)
Thank You
Felicity

Hello,
You need to go for 'Homogeneous System Copy' to achieve this, but since almost all the systems in your landscape include the Java Stack as well - so the system copy with Export/Import is to be carried out.
Even if you are not going for file system change, but it is a Windows environment and you can't put SAP up on the target Windows (windows 2008 R2) just by copying the contents and file system from source to target. You need SAPinst to create the registry and all. - On top of that you have Java stacks involved, so for java stack you can't carry out just backup/restore method to put SAP up there on target - so you need Export/import because for java stack some OS level dump is to be collected during system copy from source and it needs to be imported on target OS.
Are you clear on this one ?
Read system copy guide once and Search in OSS for the Notes to check how to upgrade from Windows 2003 to Windows 2008 R2.
Thanks

Panther server, move from single drive to RAID 1

Hello,
I am trying to find out if this can be done on a system (Xserve G3) with Panther server running on it. I know this is old, but right now the school will not upgrade the server.
It has the original 60GB hard drive and is running out of space. I would like to replace it with two 500GB HD's using software RAID.
In Panther, can you clone or CCC the OS and move it to a RAID1 from a single drive, or do we need to install and configure a new installation on the RAID set?
Any help would be greatly appreciated.
Mike

There were major changes in Disk format from 10.3 Panther to 10.4 Tiger, especially in RAID drives. I believe the 10.4 Server Installer converts your Boot RAID (if applicable) but does not deal with your data-only RAID drives. In the case you are proposing, the upgrade from 10.3 to 10.4 may require you to copy your data-only RAID drives yet again.
My older SCSI RAID drives which ran fine in 10.3 were not recognized as having a valid Driver (of any description) in 10.4. The old drives could not be mounted, and therefore could not be "promoted" to 10.4 RAID Drives. Luckily, RAID tools in 10.4 Tiger are much improved.
Using only one additional full-size drive, I was able to move the array to a spare Mac, install 10.3 to get them recognized, then Network-mount and copy them onto a single-member RAID array in 10.4 Server. Creating a single member of a Mirrored Array required some fancy command-line work in 10.4 Server.
The bottom line: If you can upgrade to 10.4 Server first, it will be much less work (and much less risk).

SAP Server Backups from Emergency Area

One of our clients is stuck in a emergency area. It is impossible to move the server right now to some safe place. Client has very limited internet access. Database backups are impossible to send. So what options we have to take as backup? Should we take daily TB and PNL reports or GL Ledger Balances Report and email these for safety reasons? Please advise.

Hi,
Please refer available back up types and choose as per your condition.

Reconfigure the Oracle streams incase of Server move from 192 to 191

Hi All,
We have bi directioanl oracle streams setup between two databases.
Recently, We have moved our server from cin192 to cin191. After server moved we checked the all the streams process.
Capture process shows Wating for Dictionary Redo First SCN XXXXXXXXX on both the database.
When i checked these SCN ,i got cin192 archive log.
Can you please help how can i resolve these issue..
Do we need to reconfigure the streams or we can assign new SCN to capture process without dropping anything with cin191 server archive log file...
Means , How to point new server archive log file to capture process..
Any help would be appreciated...
It's urgent...Plzzzzzzzzzz Help.
Thanks,
Singh

Hi Singh,
If I would know what cin191 and cin192 are, I would probably be able to redirect you to the right forum.
If you are looking for Oracle streams, I suggest you to try the Database - General forum: General Database Discussions
If is Oracle replication what you are looking for, please check here: Replication
This is the Berkeley DB High Availability forum ( http://www.oracle.com/technology/documentation/berkeley-db/db/ref/rep/intro.html )

SAP Client to the SAP Server: internal Error (-1102)[Message 131-183]

Hi,
We are using Windows 2008 Server R2, SQL 2008 Standard, SAP B1 8.81 PL08.
When we trying to connect SAP Client to the SAP Server. There has internal Error (-1102) occurred. We can view the database on client, but we always get the same error message after enter the User ID and Password. We have checked the native client and it is installed and also opened the following ports: 1433, 30000, 30001. We have tried to open all of firewall, but itu2019s no use.
When I set a computer in to the engine room and set the network connection, this one can connect SAP Client to the SAP Server.
But when client connect to server by VPN, the IP address will not in the same section. Then We tried to set the IP address has the same network section with the server, but it's still disable.
I set a computer for SAP Server without firewall, complex network, virtual IP and no router in my office. And use a SAP Client which is in different network domain to connect to SAP Server by internet, not VPN, but the SAP Client still canu2019t connect to SAP Server. I get the same internal Error (-1102).
It can not only ping to SAP Server IP, but telnet to the port 1433, 30000, 30001, 445.
When I use a pc with server tools, it can connect to the SAP Server by the localhost license. But if I use a computer only install client and assign the server license. The latter one always got the error.
How could we solve this problem? Is there has another setting I am missing which might be blocking the connection?
Thanks in advance.

Hi,
We are using VPN and using Terminal Licensing or Remote Desktop Conneciton.
The idea here is VPN will connect you to the network and when you are connected to the network
dont use the direct LAN IP connection use the Terminal Licensing to connect.
Again both are needed VPN and Terminal Licensing. VPN for the connection and if successfully connected
use or connect from Terminal Licensing or Remote Desktop connections.
Thanks.
Clint
