native VLAN 1

I'm in the process of setting up UCS.  The default native vlan has a vlan ID of 1 in UCS.  Our native vlan is 1000.  So I setup a new vlan with the vlan ID of 1000 and set it as the natvie VLAN.  I cannot delete the VLAN default (1) even though it isn't the native vlan anymore because UCS won't let me.  We use VLAN id 1 for some of our corporate servers so I can't create a vlan with that ID without an overlap.  Since it's not being used as the native vlan anymore can I go ahead and use VLAN default (1) or is there some issue with me using that vlan?

Additionally, one other question in regard to the natvie vlan.  I setup another UCS environment and have a few ESXi servers running on it with some active vm's.  When I setup UCS I added a vlan for our companines native vlan (vlan id 1000), but I forgot to set it as the Native VLAN.  So VLAN default (1) is still listed as the Native VLAN.  What implications would there be if I changed the Native VLAN to the vlan I setup (vlan id 1000) while there are running ESXi servers and virtual machines.  Neither the ESXi servers or vm's are using either on of those vlan's in service profiles and vnic templates.
