We have just started ECC 6 EhP4 to EhP7 upgrade project. We have EhP4 production support landscape and have setup a parallel EhP7 landscape for the upgrade. In order to sync upgrade development with production changes, we plan to import production transports (EhP4) into upgrade development (EhP7). I have done some research on this and have read notes 1090842, 1688610 and KBA 1742547, all these notes suggests there is no issue if moving a transport from lower to higher version.
I want to ask folks who have done similar upgrades and what approach you followed. How did you keep upgrade development with production changes? If you moved production transports, was there any issues such as objects inconsistencies, data loss, any other technical or logical issues? I just want to make sure we won't run into these issues if we decide to bring EhP4 transports into EhP7 systems.
Thanks
