Abstract [sv]

Studien undersöker fenomenet migrering av legacy-system till molnlösningar. Ettlegacy-system är ett föråldrat IT-system som fortfarande använder äldre typer av teknikäven då mer modern teknik finns tillgängligt. Dessa system används vanligtvistillsammans med äldre affärssystem samt inom lager och produktionsmiljöer.

Utifrån tidigare forskning på området identifierades det en lucka i litteraturen hursvenska konsultbolag inom IT-sektorn hanterar och genomför migreringar av legacysystem till molnlösningar. Denna undersökning tillämpade en kvalitativ intervjustudiemed semistrukturerad intervjuform och en tematisk analys genomfördes. Litteratursamlades även in kring tidigare dokumenterade utmaningar och metoder för att skapagrundläggande förståelse inom ämnet.

Studien ämnade kartlägga vilka utmaningar, metoder och hantering av utmaningar IT konsulter möter i deras arbete. Denna studie identifierar totalt tre tillvägagångssätt förmigreringar, först en förstudie, sedan två olika metodval, Rehost och Replace. Vidareframförs även totalt nio olika utmaningar samt vilka tekniska åtgärder konsulter utför ihanteringen av dessa. Studien bidrar även med att öka antalet studier mot näringslivetgenom att djupare undersöka svenska konsulters arbete med migrering av legacysystem.

Abstract [en]

This study investigates the phenomenon legacy-system migration to cloud solutions.Legacy-systems are described as an outdated IT-system which still uses older types oftechnology even though more modern technology is available. These systems areusually found in older ERP-systems, as well as in warehouses and productionenvironments.

Based on previous research in the field, a gap was identified in the literature on howSwedish consulting companies in the IT-sector handle and implement migrations oflegacy-systems to cloud solutions. This study applied a qualitative interview study withsemi-structured interview form and a thematic analysis was conducted. Literature wasalso collected around previously documented challenges and methods for creating basicunderstanding of the subject.

The study aims to identify challenges, methods, and the management of challenges IT consultants face in their work. The study presents a total of three different methods,first a feasibility study on migration, then two different method choices, Rehost andReplace. Furthermore, a total of nine different challenges are presented, as well as whattechnical measures consultants perform in handling them. The study also contributes toincreasing the number of studies towards the industry by examining in more dept thework of Swedish consultants on the migration of legacy-systems.
