Abstract [en]

Retirement of old IT - systems to newer ones has become more up-to-date, due to increases in performance in hardware and new programming languages. Nevertheless for companies it is not uncomplicated how this retirement process is best handled, and there are not many studies covering this phenomenon. In this thesis the goal is to find general guidelines regarding retirement of IT - systems. This is done by doing a case study on retirement for the old (MAPPER/BIS) platform to a more modern C# system which is currently used at Handelsbanken, one of Sweden’s largest banks.

With the help of a qualitative research method, literature study and with interviews at Handelsbanken and external parts, we aim to understand and analyze what’s important in a retirement process. In order to create recommendations for our guidelines by also using some parts from the EM3: Software Retirement Process Model.

The result of the thesis report is in total 16 guidelines that are presented as tables in the study, which companies can use in their retirement process. Ten guidelines are concerned with the retirement of the platform and six guidelines regarding conversion rules. Nonetheless the study has shown that not all systems on the MAPPER platform were possible to retire. 

Abstract [sv]

Pensionering av IT-system har idag blivit en mer aktuell fråga än någonsin, till följd av att system blir gamla och inte är anpassade till dagens hårdvara eller moderna programmeringsspråk. Det är inte okomplicerat hur en sådan pensionering ska ske, speciellt då det inte gjorts så många studier kring det ämnet. I denna uppsats är målet att ta fram riktlinjer gällande pensionering, detta gjordes genom att utföra en fallstudie. Fallstudien gjordes på uppdrag av Handelsbanken, en av de största bankerna i Sverige, kring pensionering av (MAPPER/BIS) plattformen till en annan mer moderna plattform i C#.

Med hjälp av en kvalitativ forskningsmetod, litteraturstudie samt intervjuer med personal på Handelsbanken och externa parter, ämnar vi att förstå och analysera vad som är viktigt vid en pensioneringsprocess. För att kunna skapa rekommendationer till de riktlinjer kring pensionering som detta arbete presenterar. Vissa utvalda delar av EM3: Software Retirement Process Model kommer också att ligga till grund för riktlinjerna.

Uppsatsrapporten har resulterat i totalt 16 riktlinjerna som presenteras i tabeller som företag kan använda i sina pensioneringsprocesser. Tio stycken riktlinjer grundar sig i pensioneringen av en plattform och ytligare sex stycken gäller konvertering. Studien visade dock att alla system på MAPPER plattformen inte var möjliga att pensionera.
