Hi，Dear Sir/Madam,
customer want to implement a new ACI datacenter core layer to replace old catalyst 6509 core, many business running on old core, and it is required to run 7x24 ， and migrate is smooth and quiet.
we think we can connect a temp layer 2 trunk to aci border leaf , and create different tenant for different business, and direct traffic to appropriate VxLAN.
on leaf layer of ACI , we create vpc on two leaf 93 switch , and create hsrp group on leaf tenant l3out EPG, when migrate business from old network , if we want to migrate as smooth as possible ,we want to implement like these steps:
1.we can move standby hsrp address from old network to ACI HSRP,
2.hsrp active on old network form hsrp relation with hsrp standby on ACI
3.shutdown hsrp active layer3 interface . and hsrp standby interface on ACI become active hsrp, business server traffic‘s L3 gateway switch to ACI.
4、move hsrp active （before shutdown L3 interface on old network active hsrp) address to aci, and form hsrp relation ship
but I check hsrp on aci document, it doesn't support hsrp for VPC on ACI.
is this possible？
how can I migrate old business server from old Network to new ACI architecture as smooth as possible？
thank you！
Jeremy
