Migrates an infra or infra_internal gclient to an infra_superproject one.
|
|
|
|
Does an in-place migration of the cwd's infra or infra_internal gclient
|
|
checkout to an infra_superproject checkout, preserving all repo branches
|
|
and commits. Should be called in the gclient root directory (the one that
|
|
contains the .gclient file).
|
|
|
|
By default creates a backup dir of the original gclient checkout in
|
|
`<dir>_backup`. If something goes wrong during the migration, this can
|
|
be used to restore your environment to its original state.
