Old Ranking and Play Data Migration
Recently, we updated social login and introduced a new overall ranking system.
Many players are enjoying the update, but we understand that some of you miss seeing your previous rankings and records.
To address this, we’ve prepared two pages:
one to view the previous rankings, and another to apply for play data migration from your old records.
Old Ranking: https://rank.o2jam.com/content/leaderboard/player/overall/
New Ranking: https://rank.o2jam.com/content/leaderboard-new/mastery/overall/
📥 Apply for Old Play Data Migration
Because the new login and ranking systems are quite different from the old ones,
automatic play data migration is not currently possible.
If you wish to migrate your previous play data, please apply through the link below.
We’ll process migrations sequentially after receiving your requests.
Application period: From October 18
Migration processing period: From October 23
It may take around one week to complete the migration after applying,
and the processing time may be longer depending on the number of requests.
