[Zope] import / export between versions

Hello friends, please help me. I have Zope 2.3.3 on my localhost and zope 2.4.0 is installed on my companys server. Now if i try to export files from my localhost(zope2.3.3) onto server (zope2.4.0) it doesn't work. i guess because of difference in version. Is there any solution to this problem besides upgrading to zope 2.4.0 ?? Thanks.
