Import data from Kmymoney
There are no tool available to imort data from kmymoney. so, migration from kmymoney is difficult when we have huge data.

I would recommend to migrate through GnuCash desktop.
Export your KMyMoney data to QIF, import it into GnuCash desktop.
Then save GnuCash XML from the desktop and open it within the app.
