System Requirements

A content migration with migration-center always involves a source system, a target system, and of course the migration-center itself.

This section provides information about the requirements for using migration-center in a content migration project.

For best results and performance it is recommended that every component will be installed on a different system. Hence, the system requirements for each component are listed separately.

The required capacities depend on the number of documents to be processed. The values given below are minimal requirements for a system processing about 1.000.000 documents.

Database Server

Category	Requirements
RAM	4 GB of memory for migration-center database instance
Hard disk storage space	depends on the number of documents to migrate roughly 300MB for every 100.000 documents
