Hello,
I have been tasked from moving our current production installation to a more
robust/modern installation. Any and all help would be appreciated!
Currently:
-AR System 6.3 custom server (with modifications to forms User and AR System
Email Messages)
-Oracle 9iR2 non-unicode
-Solaris 9
-Application and Database reside on the same machine
Goal:
-AR System 7.1 or 7.5 (With form modifications intact)
-Oracle 11g unicode
-Linux Redhat 5
-Application and Database on different machines
-Disaster Recovery (DR) backup site (Using Oracle log-shipping)
-Local High Availibility (HA) backup server (server groups?)
I have at my disposal 4 Virtual Machines (VMs) to do development and testing,
with an additional 2 VMs and 2 dedicated servers (for the DBs) reserved for the
final production installation. (Please note that there will be Midtier servers
involved in all of this, but their deployment is trivial so I'm not including
them here.)
>From my point of view I see that multiple operations must occur for this
>migration to be successful (in no particular order):
1) The Oracle 9iR2 DB
-Must be upgraded to 11g
-Must be translated into Unicode
-Must be moved from the Solaris 9 machine to the Linux RH5 machine
2) The current 6.3 installation
-Must be upgraded to 7.1 or 7.5
-Must be configured for server groups
-Must be moved from the Solaris 9 machine to the Linux RH5 machine
-Must begin connecting to the DB remotely instead of locally
3) The finished AR System 7.x installation and Oracle 11g DB
-Must begin log shipping (Data Guard) to the second DB
-Must have a method for failing over to the second site
-Must have a method for local server group failover (load balancer/quick
TTL DNS)
If you have completed any one of these tasks before, *please* share with me
your experience and what you would recommend for my situation! I would save
me hours of researching dead-ends!
Finally, I would like input on what would be the correct order to complete all
of these tasks, so that the cutover would be as smooth as possible with the
least downtime possible. So far, I have tested the following scenario in
Dev/Test:
Fresh installation of 7.1/7.5
-DEF import of workflow
-ARX import of data
This method seems stable but tedious, as there are many import errors I would
need to repair. This would be the method I would fall back on if there were no
more clever/sophisticated way to upgrade.
Again, ANY input at all would be GREAT, as of course this project is on a tight
timeline. THANK YOU to anyone who responds!
