Is it mandatory to stop sender channel during PI server downtime

Hi All,

I have some doubts regarding PI Server downtime activities. Currently I am working on 7.31 Dual Stack but 95 % interfaces are in ICO.

Ques :-  It is mandatory to stop all sender channel ?

Ans :-  Yes since Data will be lost

Doubt :- Where Data will be lost we have three cases .

1. Message are picking from sender side

2. Message are processing in PI

3.Message are receiving in Receiver.

In all the cases if we will not stop the channels but stop server it self , message will be failed in  sender and receiver system or in PI system

1. For all sender /receiver  system have these configuration either message will processed completely or roll back .

2. If Message will fail in PI we can reprocess that message

So now the question, is it still important to stop sender and receiver channel if yes then why ?

Thanks & Regards,

Rudra
