The decision to play two matches instead of the usual one was taken after discussions between the KNVB, both clubs and local authorities in Amsterdam and Rotterdam.
Ajax will host Feyenoord on April 25 with the return in Rotterdam on May 6. Both matches will be played without fans from the visiting club.
"The enormous costs of security and the flaring up of hostilities between both fan groups in the last few weeks are the reasons for this decision which is supported by all involved parties," KNVB-director Henk Kesler told a news conference.
"Also the Minister of Home Affairs showed great concern about the costs of approximately one million euros for security and the possible social unrest."
Since 1989 the Dutch Cup final has been held at Feyenoord's home stadium in Rotterdam.
