FAQ: whether V1R5 edition upgraded by the old platform USG2130 VIR2 edition can make VRRP with the new platform USG V1R5
Not suggest that V1R5 edition upgraded by the old platform USG2130 VIR2 edition make VRRP with the new platform USG V1R5. Because the storage have a large difference between new and old device. If it upgraded to R5 and make the VRRP, then 512M device as the primary device and the 256M device as the secondary device, there will be a risk that 256M device storage is not enough to use (such warning, packet loss, restarting). In addition, the function between 512M and 256M storage devices is different.
The most reliable method is that make the VRRP between old and old devices, or between new and new devices
