012/**
013 * Creates the "Administration" workspace.
014 * Runs only in CLEAN_INSTALL mode.
015 * <p>
016 * Part of DM 4.8
017 * <p>
018 * Note: when UPDATEing to 4.8 the "Administration" workspace is created in migration 12.
019 *
020 * ----------
021 *
022 * Originally this migration created the "admin" user account (part of DM 4.5).
023 * Run mode was CLEAN_INSTALL as well.
024 * <p>
025 * Now the "admin" user account is created in migration 10. At this moment both must exist, the "Login enabled"
026 * config topic type (created in migration 9 as of DM 4.7), and the "Administration" workspace (created here).
027 * <p>
028 * Note: when UPDATEing to 4.5 the "admin" user account already exists.
029 * It was created via postInstall() hook (which is obsolete in 4.5)
