=head1 NAME
|
|
|
|
merge-users.pl - Merge two user accounts.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
This script moves activity from one user account to another.
|
|
Specify the two accounts on the command line, e.g.:
|
|
|
|
./merge-users.pl old_account@foo.com new_account@bar.com
|
|
or:
|
|
./merge-users.pl id:old_userid id:new_userid
|
|
or:
|
|
./merge-users.pl id:old_userid new_account@bar.com
|
|
|
|
Notes: - the new account must already exist.
|
|
- the id:old_userid syntax permits you to migrate
|
|
activity from a deleted account to an existing one.
