Latest tricks for SAP HANA Migration for an abridged IT environment And, don’t forget the consultant’s expertise!

Appropriate implementation is the key to SAP HANA’s successful results. Its value can only be judged by someone who has the expertise and can officiate its implementation keeping in mind at least 5 factors which make its utility essential for a simple, working IT environment. This blog also simplifies the explanation process for ideal SAP HANA Migration. 

DMO migration technology or Heterogeneous System?

Now that the five factors clear the decks, which technology could be used? If the migration is from a non HANA set up, then DMO (data migration option) of software update manager or heterogeneous system copy of software provisioning manager are used. The former is preferred without the system update.

DMO without System Update

using Software Update Manager

Heterogeneous System Copy

using Software Provisioning Manager

 Easy to use, recommended by SAP

 Complex procedure

 No consultant certification required

 Only for certified consultants

 Change of App Server host possible

 Change of App Server host mandatory

 Shadow system used

 No shadow system necessary

 Change of System-ID not possible

 Change of System-ID possible

The DMO is capable of using its own logic for Sap HANA Migration. It works with R3load pairs and can run on the same host. It can create a shadow system,

A consultant is required for heterogeneous system to understand the procedure. It needs a change of App server and additional hardware. It is a technical expertise that can be organized by the consultant. The complex nature of the installation is best done by him. Those who have experience for at least ten years and have knowledge of all the HANA migration are useful vendors. They use few steps for the successful integration on the platform.

The steps involved are:

1.        Every business has a different scope of SAP HANA Migration. Once this is understood, the consultant can do a better job. Technology can be expensive to install and maintain. Hence, it is best to have customized plans for migration. HANA has the capability to compress large amounts of Data in memory. So how much memory is required is of consequence. This knowledge will simplify the process.

2.        Right in the beginning it has to be determined where the migration will occur. Once the platform is determined-weather cloud or on site, the company knows how much control it has over the systems. On premises, there is more control. When it is on cloud the flexibility and scalability is huge. Take the advice of the consultant to use one of the either. SAP also offers a cloud option. This could be factored.

3.        Before migration ensure that data which is not required is deleted. The purging process will make the system cleaner. It will offer solutions and not confusion while the process is on. Even the cost of licensing reduces along with it.

4.        Set up a flexible time frame to get the migration process going. Often data gets erased or some may get duplicated. The coding changes and it may take up time. A flexible schedule will ensure that the technicians avoid all kinds of data errors. 

5.        There should be ample time for a trial run before actual deployment. This can be done in isolation or on premises. The coding can be mimicked for the technical projects. When the actual deployment takes place, the validation will be 100%.

Value base for technical migration

Most enterprises use the classical migration which is the heterogeneous system. It uses tools like R3load, SWPM and Migration Monitor. If no new component is required or no upgrade is required, then the classical migration is the ideal way to proceed. If it is the very first time, then a brand new installation will be recommended by the consultant. There should be a consistent approach for the SAP HANA migration which will not impact the technical issues that appear with selective data. Companies that already have various AP processes this can be a value addition. The best advice here would be having a smaller digital footprint on the cloud with migration. But don’t forget to clean the datalog if you want optimum output for operations. It will make the digital structure work more efficiency and reduces business downtime. If quality and performance matter the most, then use this migration for the best IT environment practices.
