DB2 LUW will perform differently on Windows than on AIX due to the different hardware and OS software and so it will need to be configured in a different way to optimize performance. I have worked with companies that run DB2 LUW on AIX servers and Windows servers just fine. You just have to configure things a little differently.
DB2™ (NetBoost for AIX) allows DB2 servers to integrate with InfiniGuard disk backup systems. Once installed and configured, a DB2 server can manage backups through the InfiniGuard system and take advantage of the system’s capabilities such as client-side data deduplication and replication.
taken at 2015122923463 Working with DB2 on AIX for our SAP AFS Application. Approx. 4TB database split over 4 logical volumes in an IBM Virtual IO environment on IBM Power. This backup takes 20 to 26 hours.
DB2 is installed in /opt/IBM/db2. If you want to install Db2 as a non-root user, have your system administrator complete the following tasks on the target server before you begin the installation: If you are installing Db2 on an AIX server, install sudo on the server. The default AIX distribution does not include sudo. To install Db2 on the AIX operating system by using a command prompt, complete the following steps: Log in with a user ID that has root authority. Installing DB2® on AIX®, Linux™ or Windows™ IBM® Sametime® on AIX®, Linux™ or Windows™ requires the use of an IBM DB2® server. Databases store information about users, Sametime servers, configuration settings, and meetings.

We want to migrate a (SAP) database from AIX DB2 V7 to SUSE 10 DB2 V9.
We are thinking about using the db2move to do this.
Is this possible?

Maximizing Load Performance for DB2 under UNIX and PC Hosts These tips can help you optimize LOAD performance when you are using the DB2 bulk-load facility. Specifying BL_REMOTE_FILE= causes the loader to use the DB2 LOAD utility, which is much faster than the IMPORT utility, but it requires database administrator authority.

after looking at this and setting this $ su - db2inst1 $ db2set DB2TCPCONNMGRS=1 To quote " the difference was UNBELIEVABLE !!!". Thanks Eric. Many AIX applications use IBM Db2 as the database, while others use Oracle, IMS DB, Informix, or other databases. Since Db2 LUW (Linux, UNIX, Windows), Oracle, Informix, and IMS DB run on Linux, the migration path is straightforward.

Progress DataDirect’s ODBC Driver for IBM Db2 offers a high-performing, secure and reliable connectivity solution for ODBC applications to access IBM DB2 data. Our ODBC driver can be easily used with all versions of SQL and across all platforms - Unix / Linux, AIX, Solaris, Windows and HP-UX. I had made backup from remote IBM DB2 server in AIX using this command: ./db2 backup database DBEMP to /home/dbemp/backup Then I grab the backup file using FTP Client from my Windows.
