Cloning /Replciation SAS Servers

Hi Champions,


(I am have the 3 Machines one Machine having metadata tier , one Machine having midtier & one Machine having compute- tier , all in OS is REHL)----old environment
(New environment need to clone metadata tier , compute tier and mid tier need install & configuration ) –new environment


Approch

1 first step install Os in new environment 3 machines

2 take the back up for all tier from old  envirionment

3 Replication/ clone the mid-tier and compute-tire, metadata tier , mid-tier (with out os all sas binareies coped form old to new


Re-configure SAS Metadata Server and Compute Tier related Configuration Files to point to new Environment ,

Update the local service accounts passwords using SDM, Unconfigure mid tier environment (WAS)

is there any OS (REHL)  setting need to change in new environment ?


Note : Here all domain names are same (old environment and new environment) expect ips

         
Can please suggest me what are the challenges in this approach, if you can it is great helpful for me


Thanks in Advance

Re: Cloning /Replciation SAS Servers

I take it you've got separate 9.2 and 9.3 environments, which you're trying to clone to equivalent 9.2 and 9.3 environments on the new server machines.  When you say you're going to reconfigure the metadata and compute tiers, and all things being equal between old and new systems, you really only need to take care of hostname references via the SAS Deployment Manager (assuming those have changed).  What you're describing matches Use Case 2 of http://support.sas.com/documentation/cdl/en/bisag/64088/HTML/default/viewer.htm#a003361855.htm (for 9.2) and

http://support.sas.com/documentation/cdl/en/bisag/65422/HTML/default/viewer.htm#n0zdcqxsmd21wtn17vt0... (for 9.3).


I'm not sure why you mention unconfiguring the WAS middle tier, unless you're talking about unconfiguring it on the old middle tier.
