RISC to Intel migrations

[AmitShelly]

Hi,

Anyone has any documents / artefacts on RISC to Intel migrations (migrating Enterprise Apps from RISC platforms to VMware virualization platform)?

Really appreciate if you could share them.

I am more keen in getting RISC based server assessment templates, typical migration scenarios / case studies, challenges faced & mitigation plans.

Thanks in advance.

Cheers!

This kind of migration require (in most case) a complete application rebuild to the different architecture.

Yes true...Which is why I am working on preparing some standard templates / assessment checklists which can be used during such migration project assessments. And, I would need help from experts like you in preparing these.

Cheers!

In this case, you must analyze each service.

Usually you have multi-tiers services, so for each service you have several other dependency (still services).

At this point you have a complete list of each service and you can analyze how is implemented:

- for DB level you must if vendor software exist also on Intel or if the application could be adapt to a different DBMS solution (there are both the problems of "SQL" portatibily and data connections reconfigurations)

- for the business logic and presentation layer it depends by the container and the language that has been used. For a J2EE platform could be simple port to a Intel server, but still there could some dependency, like the usage of specific classes or library or functions.

Then there is a complete checklist of the code of your programs:

- language is portable?

- do you have the sources? Needed for compiled binary, but in some case could also be needed for bytecode programs.

- which libraries/modules/classes are used, are those portable?
