Hi @gowdakssujan 

In this discussion of the community there was much talk about this topic:

Hi,

VTP client and server systems require VTP updates from other VTP servers to be immediately saved in NVRAM without user intervention. The VTP update requirements are met by the default CatOS operation, but the Cisco IOS software update model requires an alternative update operation. For this, a VLAN database was introduced to Cisco IOS software for Catalyst switches as a method to immediately save VTP updates for VTP clients and servers. This VLAN database is in the form of a separate file in NVRAM called the vlan.dat file.

BTW, clients can be a source of a VTP update in VTP versions 1 and 2.
