hi, Laurence<br><br>Thanks for your reply. But the export/import mechanism is not suit for my situation.<br>My site is now a very complicated system and 'huge'. Zope's export/import mechanism is <span class="wbtr_mn">fragile, I never export a so large site successfully</span>.<br>
<br>Now maybe I have three choices:<br>1. Understand all codes in fspack.py and implement the 'turn off gc when packing' function on ZODB3.6.2;<br>2. Update my ZODB version from 3.6.2 to 3.8 or later to try use 'zc.FileStorage' ;<br>
3. Convert my site to use 'RelStorage', and use its 'turn off gc' option to pack my site.<br><br>Yesterday I tried choice 1, but I am not familiar with 'FileStorage' format and can not implement the function myself in a short time( I have done 'Plone' development for years, but I am not so familiar with the underlayer knowledge about 'Zope' ).<br>
<br>For choice 2, I have one question: Is high verstion ZODB(3.8 or later) compatable with low version ZODB(3.6.2)? I googled but not find those compatability information.<br><br>For choice 3, 'RelStorage' provide a 'ZODBConverter', but I do not to know if it can used with ZODB3.6.2?<br>
<br>Thanks<br><br>eastxing<br><br><div class="gmail_quote">2009/1/21 Laurence Rowe <span dir="ltr"><<a href="mailto:l@lrowe.co.uk">l@lrowe.co.uk</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

</div></div>As an alternative to backporting the changes to pack, you could try<br>
doing a zexp export of the site, and then reimport the zexp into a blank<br>
Data.fs.<br>
