Hi folks,
I had deleted my bench (name it as B1) by mistake after something went wrong during bench B1 update.
There were 2 sites created using the deleted bench B1.
Now, I installed new bench (name it as B2)and trying to run the 2 instances which was installed using bench B1.
It is not working.
Installing 2 instances on bench B2 will again take almost 3 hours.
Any workarounds, when i delete my bench (not purposefully. 
)
Thanks in advance!!!
PS: Never delete your bench as per my observations.
