If anyone have checklist then please comment below.

Thanks in advance.

Hello @india2016,

I would understand you would like to know just about the migration part, not the installation of the new server on Linux.

For the migration: most of the VA items are just metadata, therefore they should be OS independent, like a normal promotion. If you know how to promote the metadata, you got it. If not, that is a different question. Please let us know if you need information about general promotions.

They things that are different on Linux:

• the installation, which I understand an experienced consultant will do it.
• The availability of Hadoop and a distributed LASR for High performance, if you seelct the distributed version of VA (on windows, you have got only the option of VA non-distributed)
• Scripts on Linux code: if you have got custom scripts, you will need to translate them from Windows to Linux. And for that you will need a Linux expert.
• The scripts for the VA deployed queries: you will just need to re-schedule them (and the new schedule will be at as default, or cron).
• Very important: it will be better to migrate all your SAS datasets to Linux. Not really required, but a best practice.

Could you please explain how we make checklist for migration planning.Our migration will be done by administrator but I need to provide him checklist only.

Hi @india2016,

I could give you a quick checklist, and I will, but let me give you first the 9.4 Migration guide http://support.sas.com/documentation/cdl/en/bimig/69173/HTML/default/viewer.htm#titlepage.htm

For you to know, there are 2 main wais to migrate: partial promotion (export and import spk packages from the SAS Management Console), or the SAS Migration Utility (SMU). For VA I would recommend the partial promotion because you can remain more in control, and it is not much extra time from SMU.

In short, very short (you should read the document):

- Install SAS VA and validate the installation on Linux.

- Implement integrations with your Active Directory and other systems (as your db drivers/connections, etc).

- Migrate your SAS datasets from Windows to Unix.

- Move your SAS code.

- Ensure permissions are fine on Linux for your code and SAS datasets.

- Migrate metadata security (users, groups, ACTs, etc).Ensure your Outbound access paswwords are filled manually.

- Migrate other things as Auth Domains and deployment folders

- Migrate metadata folders (empty folders)

- Migrate server definitions (your databases, settigs of your SASApps, etc)

- Migrate your meta libraries and ensure they are attached properly to the right connections.

- Test your libraries

- Migrate your metadata table definitions for the libraries.

- Migrate custom transformations, if any.

- Migrate your jobs/ queries/deployed jobs or queries/stored processes, and report-related items, as graphs (not the reports)

- Migrate your reports

- Migrate your distribution lists

- Re-schedule your queries and test they can be loaded into LASR.

- Test your environment, and reports.
