Compatibility with prior versions

There are some compatibility issues between dump files and Backup Server. Table 27-12 indicates the dump file formats that can be loaded by the current and previous versions of local Backup Servers.

**Table 27-12: Server for local operations**
	New dump file format	Old dump file format
New version of server	Yes	Yes
Prior version of server	No	Yes

Table 27-13 and Table 27-14 indicate the dump file formats that can be loaded by the current and prior versions of remote Backup Servers. In a remote Backup Server scenario, the master server is the Backup Server on the same machine as the database and Adaptive Server Enterprise, and the slave server is the Backup Server on the same remote machine as the archive device.

Table 27-13 indicates the load operations that work when master server is the current version of Backup Server.

**Table 27-13: New version of master server**
	New dump file format	Old dump file format
New slave version of server	Yes	Yes
Prior slave version of server	No	Yes

Table 27-14 indicates the load operations that work when the master server is a prior version.

**Table 27-14: Prior version of master server**
	New dump file format	Old dump file format
New slave version of server	No	Yes
Prior slave version of server	No	Yes
