Why you need an airtight SAP data management strategy before migrating to SAP HANA

Friday, May 12th, 2017

 

SAP HANA is a powerful appliance that can improve how efficiently your business accesses and interprets its data, minimising downtime and resource usage. It allows real-time analytics that delivers considerable business value to your organisation – but this all depends on how much data you carry over with you to SAP HANA, and your approach to SAP data management prior to migration. Move over with too much data, and your ability to extract maximum value from the appliance is severely hampered. This can be avoided by implementing an airtight SAP data management strategy before migrating to SAP HANA.

A SAP data management strategy will streamline your migration to SAP HANA

Implementing a SAP data management strategy ahead of your migration to SAP HANA might sound like extra work that could waylay the process, but it is an important ingredient in ensuring that your SAP data is transferred with as little downtime as possible. Not only that, but a sound SAP data management strategy will also help you extract maximum value from the appliance post migration.

Migrating redundant data over to SAP HANA wastes time and resources, and increases SAP TCO

Even if you could move all your SAP data over to SAP HANA, it wouldn’t be the most effective way to manage your data. The larger your repository of SAP data, the more expensive and slower the migration will be, and you’ll have less memory space on the new appliance. Your size requirements for the HANA appliance will also be higher, which will vastly increase your setup and running costs, and total cost of ownership (TCO). If you invest time in streamlining your data prior to a migration, you’ll free up time and resources that would have otherwise been spent on migrating redundant data over to the new appliance.

By implementing a data management strategy for SAP, you avoid downtime now and in the future

A SAP data management strategy – that includes SAP archiving – sorts your current SAP data into that which is required, and that which isn’t needed on the new appliance. By reducing your SAP data, you enjoy faster backups pre-migration, and a quicker migration period that reduces overall downtime during the transition period to SAP HANA. This equates to greater cost savings, less pressure on your department, and eliminates the chance of encountering technical hitches along the way.

Reduce SAP HANA size requirements by implementing a data management strategy prior to migration

Getting your size requirements right for the SAP HANA appliance is an integral part of keeping down costs and enjoying the maximum benefits afforded by SAP HANA. To reduce your SAP HANA size requirements, business-complete and obsolete data can be moved, as part of a SAP data management strategy, onto lower tier storage so that it needn’t be included in the migration. Do this ahead of migration and you’ll streamline the transition; try and implement it during the transition and the whole process becomes very resource heavy. That said, if you’ve already migrated to SAP HANA, you can still implement an archiving strategy that will reduce running costs and improve appliance efficiency.

Controlling data growth after migration enhances SAP HANA’s performance capabilities

Post-migration, your next concern is controlling data growth. There’s little sense archiving SAP data to aid the transition over to SAP HANA, only to generate the same amount of data in the months after migration. Through controlled data growth, you extend the lifecycle of SAP HANA appliances, preclude the need for memory upgrades and won’t have to worry about running out of space. With less data, you’ll also increase data access response times and appliance refresh expectancies.

Another way to reduce the work and costs involved in SAP HANA migration is to enlist the help of an organisation that understands data management and archiving. For more information about why RightSizing your SAP data is crucial before migrating to SAP HANA contact us.
