VPS

 
Why is the MQL5 VPS hosting my old EA even though I installed a new one?
 
"I installed a new one" in case of MQL5 VPS is the following: you opened the chart(s) and attach to the chart(s) new EA, and after that - provide synchronization/migration. And do not forget to look at MQL5 VPS journal after that.

Or (the second way to do) - you can open the chart without any EA attached, and provide the synchronization of this empty chart.
So, MQL5 VPS (and this VPS is your other Metatrader in cloud) will have just 1 empty chart (without any EA).
After that - open the chart(s) and attach to the chart(s) new EA and provide the synchronization/migration once again.
