Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Upgrade and Migration Guide

# File Formats

In Application Server 8.1, `domain.xml` is the main server configuration file. In Application Server 7, the main server configuration file was `server.xml`. The DTD file of `domain.xml` is found in `lib/dtds/sun-domain_1_1.dtd`. The upgrade tool included in Application Server 8.1 can be used to migrate the `server.xml` from Application Server 7 to `domain.xml` for Application Server 8.1.

The `lib/dtds/sun-domain_1_1.dtd` file for Application Server 8.1 is fully backward compatible with the corresponding file for Application Server 8, `sun-domain_1_0.dtd`.

In general, the configuration file formats are not backward compatible. The following configuration files are not supported:

- `*.conf`

- `*.acl`

- `mime.types`

- `server.xml` (replaced with `domain.xml`)
