Different UNIX-like operating systems store information about their release versions differently. If you know what OS you have, but not sure about the version, then here's how you can find out:
bash-2.03$ cat /etc/release Solaris 8 2/04 s28s_hw4wos_05a SPARC Copyright 2004 Sun Microsystems, Inc. All Rights Reserved. Assembled 08 January 2004

Explanation/Reference:
Explanation:
shadowd is a daemon that provides background worker threads to migrate data for a shadow migration. A shadow migration gradually moves data from a source file system into a new "shadow" file system. Users can access and change their data within the shadow file system while migration is occurring.
The shadowd service is managed by the service management facility, smf(5). Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.
The svccfg(1M) command can be used to manage the following parameter related to shadowd:
config_params/shadow_threads
Note: Oracle Solaris 11: In this release, you can migrate data from an old file system to a new file system while simultaneously allowing access and modification of the new file system during the migration process.
Setting the shadow property on a new ZFS file system triggers the migration of the older data. The shadow property can be set to migrate data from the local system or a remote system with either of the following values:
file:///path
nfs://host:path

Which Solaris release you are running on your system can be determined using the following command:
cat /etc/release
This will tell you which release you are running and when it was released. The more recent your system, the more info is contained in this file.
