Tips for a Successful Application Migration with STACKIT

Successfully migrating applications to the cloud requires more than just good technology. Clear structures and the right combination of strategy and expertise are crucial. These four tips will help you implement your migration with STACKIT in a targeted and secure manner:

1. Plan early - with foresight and system

A good migration strategy starts with a clear overview: Which applications, data and dependencies exist? Where are the risks and where are the potentials? The sooner you clarify these questions, the better you can manage technical challenges, security requirements or integration issues. STACKIT supports you with structured advice and practical templates for planning.

2. Automate where it makes sense

Setting up a process manually takes time and makes it error-prone. Therefore, use infrastructure-as-code, scripts and automated solutions to create test environments, roll out configurations or transfer data. STACKIT's cloud services offer you a variety of solutions - ideal for companies that want to make their migration lean, secure and reproducible.

3. Security as a consistent principle

Whether data protection or compliance with regulations - the protection of your applications and sensitive information should be considered right from the start. STACKIT makes it possible to integrate security checks directly into the planning and migration process: with role-based access rights, encryption, automated vulnerability scans and certified standards that comply with the European legal framework.

4. Work with experienced partners

The view from the outside is useful for complex migrations. Experienced partners help to avoid typical stumbling blocks, avoid problems and realistically assess risks - from the first analysis to go-live. STACKIT has a network of experts that supports companies of all sizes - whether with special requirements or as support for the entire project.
