Aplikasi e-Government di banyak instansi masih bergantung pada arsitektur web monolitik yang cukup menyulitkan dalam proses pemeliharaan sistem dan proses penyesuaian cepat dengan kebutuhan baru. Penelitian ini mengusulkan model migrasi pada sistem keuangan e-government berbasis Glue Framework (Struts, iBATIS, dan JSP) menuju arsitektur microservices berbasis Spring Boot. Dimana sedikit berbeda dengan pendekatan model migrasi microservices secara umum yang menempatkan database secara terdistribusi pada setiap service, maka pada model migrasi sistem keuangan ini mempertahankan skema basis data eksisting untuk menurunkan risiko migrasi serta memungkinkan fase ko-eksistensi, yaitu aplikasi lama dan aplikasi hasil migrasi berjalan bersamaan menggunakan sumber data yang sama selama fase migrasi sistem. Penelitian ini menggunakan pendekatan Design Science Research (DSR) dengan studi kasus pada sistem keuangan e-Government di lingkungan BP Batam. Adapun prosedurnya, model migrasi diformulasikan ke dalam enam tahap: asesmen sistem legacy, penentuan batas layanan, ekstraksi microservice, tata kelola akses basis data bersama, pemutakhiran antarmuka, serta integrasi dan validasi. Model divalidasi melalui studi kasus sistem keuangan pada sistem e-Government, dengan mendokumentasikan artefak, titik keputusan, dan strategi mitigasi terhadap kendala legacy. Kontribusi penelitian ini berupa model migrasi yang dapat direplikasi untuk membantu modernisasi sistem e-Government lain yang memerlukan integritas data tinggi dan keberlanjutan layanan.
