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 |
CPU | min. 2.5 GHz (corresponding to the requirements of the Oracle database) |
Oracle version | Oracle 10g Release 2 - Oracle 19c |
Oracle instance | Character set: AL32UTF8 Necessary database components: Oracle XML DB |
