Hi Experts of NSX,

I got some questions if someone already have experience on how to fix this kind of error. I am currently migrating from NSXV to NSXT 3.2.3.0.0xxxxx

I dont have error during the migrate configuration but on the prepare infrastructure i have this error always.

Failed to prepare infrastructure for host migration [Reason: SecurityGroup failed with '400: Another object with same name : IPv4_IPSet_DFW_VLANxxxxx_securitygroup-xxxx already exists in the current scope : globalroot-0. for url: https://xxxxxxxx.xxx..local/api/2.0/services/ipset/globalroot-0'].

appreciate your response. 
thank you
