Moving to the cloud:
Migration
strategy models
and the 6 R's
(Part 2 of a Series)
by GORDON WINGATE

I

N THE SPRING ISSUE OF WIN
magazine, we took a look at
the timing of moving a managing general agent's in-house IT
system to a public infrastructure and how that decision will
depend on the unique circumstances
of each operation. In this article, we
will examine how the migration strategy can work, and the best practices
behind them.

THE 6 R'S OF MIGRATION
The 6 R's will allow you to assign the
proper migration strategy for each application your company uses. It will help

and Shift." No changes are made other
than to move an existing server over
to the AWS cloud platform. This is
ideal for servers that are running well

or when time is of the essence and
cleanup can occur later. Companies
can often find 30 percent reductions
in cost just by moving to the cloud
even without optimization.
* Replatform: "Lift, Fix, and Shift." In a
replatforming migration you upgrade
and repair servers at the same time you
move. Servers are reinstalled for stability. Operating systems are upgraded.
Your system is redesigned to use native
AWS services for Active Directory and
databases. This approach will give you
the greatest value in an AWS migration
short of rewriting applications.
* Refactoring: Requires the most effort
but will ultimately deliver the most
benefit. Aside from startups, most
