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.
For a typical Oracle Database creation please refer to Oracle Database Creation. For more advanced topics regarding Oracle Database configuration and administration please refer to Database Administrator’s Guide.
Note that not all connectors are available on the Linux version of the jobserver.

By default, the Job Server is configured to use 1 GB of memory. This will be enough in most of the cases. In some special cases (multiple big scanner/importer batches) it can be configured to use more RAM.
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.
