2 members in the team unknowingly created 2 Vendor entries for slaesfroce (just took this for an example).

Vendor 1 as "slaesfroce" and Vendor 2 as "slaesfroce.com". Each vendor is used separately for processing different POs. Say for example 12 POs are processed using "slaesfroce" and 23 POs are processed using "slaesfroce.com" as vendors respectively. 

Now as a part of data cleaning. I want to delete either of the Vendor. Suppose if I delete "slaesroce". Will those 12 POs which are tagged to this vendor be automatically tagged to "slaesfroce.com" vendor? 

Note: Requirement is only to have one Vendor entry which is either "slaesfroce" or "slaefroce.com"
