Tamino XML Server 10.3 can coexist with all previous versions of Tamino XML Server on one computer. There are some restrictions as described in the Tamino XML Server Installation Guide (available on http://documentation.softwareag.com).
However, if you have an existing Software AG product that uses Tamino as the database engine, coexistence of Tamino XML Server 10.3 and the Tamino database engine of the other product on the same machine is not guaranteed.
It is not necessary to migrate schemas or data from version 4.4, 8.0, 8.2, 9.5, 9.7, 9.12 or 10.1 to version 10.3; it is merely necessary to set the version of existing databases. Please see the Migration Guide for details.
Important:
If you wish to migrate to version 10.3 from a version earlier than
4.4, you must migrate to version 4.4 first.
For information about migration to version 4.4 from versions earlier than 4.4, refer to the documentation for Tamino version 4.4 in Software AG's web-based Product Support System, Empower, at https://empower.softwareag.com/.
It is necessary to provide a Tamino 10.3 license file to install this version of Tamino XML Server properly. The server components do not run with license files from earlier versions of Tamino. The development components, though, can be installed without an additional license file.
As a source of valuable information and help, developers can refer to the Tamino Developer Community web site (http://techcommunity.softwareag.com/ecosystem/communities/public/webmethods/products/tamino/). There you can find discussion forums and further services.
