please reply how to deal with this
You're getting this error because the MA 5 extension is not suported in ePO 4.x - so you get this error when you try and check it in.
However this is not a problem: you don't need to upgrade the extension in ePO 4, as the MA extension will be upgraded as part of the ePO upgrade. When you upgrade to 5.3, the extension will be upgraded as well.
This is excellent from your side..So fast and so correct response.I also created a SR in support for this but there response was awful as they didnt know anything
I have upgraded successfully EPO to 5.3.0
I am very thankful to you ...Really great job
