Sameera Wijayasiri, senior systems engineer
for South Asian Technologies (Pvt) Ltd.,
has experience helping clients migrate. "In my
previous role as IBM Power Systems* engineer,
I was involved in implementation maintenance
and migration of both IBM Power Systems hardware and the IBM i platform," he explains. "Some
clients were using legacy IBM i hardware and
OSes. I identified problems and
limitations in their environments and encouraged them to move to a newer version of IBM i.
I did this by educating them on the criticality of
the situation and explaining to them the business impact they would face during disasters if
they were to rely on their current setup."
The biggest challenge with migration is
application compatibility with the latest OS
versions, Wijayasiri notes. Some versions are
old, in-house developed applications, leaving
current employees with few clues about the
"Sometimes we've had to hire programming
experts to do research on the existing applications and compatibility with new OS versions
to migrate them to the new versions," he says.
"We've also been able to win new IBM clients in
Sri Lanka by migrating/porting their non-IBM
applications to IBM i or AIX* without changing
their application. That's the beauty of IBM i-it
integrates the latest development technologies
such as XML, JSON, Node.js and PHP in every OS
release and technology refresh."

scripts and web elements like buttons to distill
what previously might have been a multistep
process into one simple button click, dropdown
select or quick navigation."
He expects to see continued growth of web
technologies on the IBM i platform over the
next few years, including an increased need
for mobile and responsive applications. "One
new area that interests me is Node.js on IBM
i," he says. "The fact that you can use the same
