---------------------------------------
Hi Shaofeng,
Could you help me review these two patch?
The patch, "copy_statistics_after_old_version_migration.patch", has been used
successfully. However, I'm not sure whether only the statistics information is
enough. And I'm also not sure whether it is necessary for us to apply this
patch to master. If later we apply the patch
"fix_bug_of_missing_cube_statistics_while_migrating_cube.patch", we don't need
the previous patch.
While as for branch 1.4-rc, the patch,
"copy_statistics_after_old_version_migration.patch", is necessary because some
cubes have been migrated.
> When migrating cube, for example from QA to RPOD, some parts are missed

> When migrating cube from QA to PROD, some parts are ignored, like table_exd,
> cube_statistics. Especially the missing of "cube_statistics" will cause the
> merging of migrated cubes runs to error.
