Determining the Adaptive Server Version

Verify that your current version of Adaptive Server is not earlier than 15.x before using the binary overlay.

If your server is at a 15.x version level, you can begin installing Adaptive Server 15.7.

Verify that your version of Adaptive Server you have is version 15.x:
- If your server is running:
```
1> select @@version
2> go
```
- If your server is not running:
```
 $SYBASE/$SYBASE_ASE/bin/dataserver -v
```
Source environment variables before executing dataserver -v.

If the result shows that the Adaptive Server is lower than version 15.x, you cannot use the binary overlay, but use an upgrade method instead. See Adaptive Server Upgrades.
