hi, Laurence Thanks for your reply. But the export/import mechanism is not suit for my situation. My site is now a very complicated system and 'huge'. Zope's export/import mechanism is fragile, I never export a so large site successfully.
Now maybe I have three choices: 1. Understand all codes in fspack.py and implement the 'turn off gc when packing' function on ZODB3.6.2; 2. Update my ZODB version from 3.6.2 to 3.8 or later to try use 'zc.FileStorage' ; 3. Convert my site to use 'RelStorage', and use its 'turn off gc' option to pack my site. 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' ). 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. For choice 3, 'RelStorage' provide a 'ZODBConverter', but I do not to know if it can used with ZODB3.6.2?
