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. Please see the Sizing Guide for more details.

Hard disk storage space (logs)

1GB + storage space for log files (~50 MB for 100,000 files)

Hard disk storage space (objects scanned from source system)

Variable. Refers to temporary storage space required for scanned objects. Can be allocated on a different machine in LAN.

CPU

2-4 Cores, min. 2.5 GHz
