VLAN 1 and VLANs 1002 to 1005 are always pruning-ineligible; traffic from these VLANs cannot be pruned.
Extended-range VLANs (VLAN IDs higher than 1005) are also pruning-ineligible.
I cannot figure out that why SW3 is not updating vlan definition from the server mode switch ( sw2) Thanks in advance.
You can't manually force updates because VTP configs are pushed based on the highest current VLAN database revision number.
Initially I had all switches configured as a SERVER.
Everything was working fine in terms of VLAN updates through out the topology.

So we should set the VTP mode of the new switch to Transparent (which will also reset its Revision Number to 0) before plugging to our network.
VTPv3 supports for extended VLAN range (VLANs 1006 to 4094).
VTP versions 1 and 2 only supports VLANs 1 to 1005.
If extended VLANs are configured, we cannot convert from VTP version 3 to version 1 or 2.
