enable VTP version 2 unless every switch in the VTP domain supports version 2.

When you enable VTP version 2 on a switch, every VTP version 2-capable switch in the VTP
domain enables version 2. To enable VTP version 3, you must manually configure it on each switch.
With VTP versions 1 and 2, you can configure the version only on switches in VTP server or
transparent mode. If a switch is running VTP version 3, you can change to version 2 when the switch
is in client mode if no extended VLANs exist, no private VLANs exist, and no hidden password was
configured.
In TrCRF and TrBRF Token ring environments, you must enable VTP version 2 or VTP version 3
for Token Ring VLAN switching to function properly. For Token Ring and Token Ring-Net media,
disable VTP version 2 must be disabled.
VTP version 3 is supported on switches running Cisco IOS Release 12.2(52) SE or later.
