An increasing amount of companies and organizations are starting to implement the use of cloud computing in their business. This trend results in that software, which was previously sold and distributed to the customers whom then had to install the software on their own computers, now is being replaced with Software as a Service (SaaS). SaaS makes software available through the customers? browsers, which results in that the service providers only have to administer a single application. The process to migrate a distributed application to a service delivered as a SaaS lacks sufficient investigation; this paper will provide some guidelines for conducting such a pro- cess. During the work on this paper, a prototype of a service delivered as a SaaS has been devel- oped with the intention to test, among other things, how a distributed relational database can be converted to a key/value pair storage. A conversion of this kind enables data to be stored locally in the customers? browsers, which relieves some pressure on the server as well as enables the application to be used in offline-mode. The paper results in three guidelines which should be considered when planning to migrate software to a service delivered as a SaaS with a local data- base; Think before you act, Don?t expose your soul and Size matters. These guidelines describe how a migration process should be planned, when an application is not deemed appropriate to migrate and when a conversion of the database is not appropriate.
