Hi Akesavan,

If you are planning to do a hardware migration on your production system (for a similar compatible architecture) you need to do a Homogeneous System Copy.

Read the System Copy guide from http://service.sap.com/systemcopy

Also, https://service.sap.com/installnw70

2. How many days will take?

That pretty much depends on your environment, hardware, availability requirements. But it shouldn't take long based on the fact that your DB is only 210 Gigs.

Hi,

To be on the safer Side Just install the New system as you installed the Old PRD keeping in mind that the OSlevel the patch level and the Sap release should be same .

Once the installation Completes.you should go with the System Refresh.

Now here are the answer of your Question.

To install New PRD system it shall take 24 hour (appox).Once the base installation is completed you can go with the system Refresh.

Offline Backup will take 2 to 3 hours.(Number of hours depends on many more things).

If you have ABAP+JAVA then you beed to take the Java Export After the Backup.(1 hour)

Then you need to get the backup restored on the New Server(2 to 3 hours)

Then run Sapinst Import.(10 to 11 hours).

Post Refresh steps depends on the landscape configuration you have.

Hi,

My question is that if you have ecc system then what other components you have in your landscape.

Like Portal,BW,SRM SCM etc.

See it all depends what all changes you have to do in this system and the other systemthat are connected to it.

Thanks
