Based on the requirement and time we have we can opt the below approaches

If we have less downtime we can go with classical migration

If we have to improve performance and to reduce migration time we can go with export and import method

If we have to reduce manual efforts we can go with DMO method

Please let me know if you want to elaborate more on these methods

There are different ways of performing the migration, depending on your current configuration. If the database is small and you are not bothered about the system downtime you can use the backup of the database and restore it to the target system.

In case you would like to optimize the migration or you'd like to have a bigger influence on the execution, then you can use the Export / Import.

Finally, you can check out my blog post about migration to Azure and see how to use DMO to perform the migration:

hello Bartosz,

there is no netweaver system upon HANA, it is just a native HANA DB , which is used by BODS and BOBJ for datawarehouse purposes / reporting purposes..

we have a 1 complete day of approved downtime.

can we use the export/import for only HANA DB migration ??? or for OS migration is Backup restore is still approved by SAP?

please help us to take a decision.

Thanks

You don't really change the operating system - it is still Linux, so I don't expect any problems. As long as one day of downtime is enough to perform the backup and restore I would go for it. That's the easiest way.
