Account transfer
Please note that even if you change servers, your summoner page from your previous server will not be transferred to the summoner page of your new server.
If you return to your original server, you may see that your stats are displayed incorrectly as they could be mixed up with your previous stats before you left the server.
Your current tier will not be reset to unranked but will be reverted to the rank you were in before changing servers. Your tier will be updated after you complete the tier placement process.
