Hi,

I have done a upgradation from ax4.0 to ax 2009.

Before upgrade i took all the backup and than ran the ax 2009 setup.than connected to existing 4.0 database.

then before upgrading checklist i copied all the customized file from 4.0 to ax 2009.

then upgade the checklist in ax 2009.

client is opened but no ax 4.0 customized reflect in ax 2009.

so what more step i need follow to upgrade it properly?

If you copied the custom 4.0 layers/code to the AX 2009 environment, regardless of the checklist, you will see either customizations or broken code.

Verify you actually copied layers/code.
