I need to duplicate (for testing) a site currently running on Windows on to Linux. This isn't a big deal. I've done the reverse direction without grief. However, on this occasion, I want to change the database connector from MS SQL Server to (mxodbc) to PostgreSQL (zpsycopgda) . Having exported the live site, I am unable to import it again in the test environment because of the following errors: WARNING ZODB Could not import class 'ZopeConnection' from module 'Products.mxODBCZopeDA.ZopeDA' INFO Script (Python) Some of your Scripts have stale code cached. Since Zope cannot use this code, startup will be slightly slower until these Scripts are edited. You can automatically recompile all Scripts that have this problem by visiting /manage_addProduct/PythonScripts/recompile of your server in a browser. Although the first error is only a warning it appears to be fatal and the import doesn't complete. I also tried following the advice on the INFO message but was told there were no scripts to update. What I'd like is for the import to complete so I can sort out the database connectors. Anyone any suggestions? The live site is running 2.7.6-final python 2.3.5 (win32) and the test site is running 2.8.4-final python 2.4.0 (linux) Thanks. -- Dale Strickland-Clark Riverhall Systems Ltd - www.riverhall.co.uk
