❶ 換個手機微信聊天記錄如何轉移到新手機上
您好，方法
1、首先把新舊手機同時連接一個網路保證網路的通常，這是第一步也是關鍵的一步，不然網路不好傳輸的過程也會導致數據丟失；
2、然後打開原來的舊手機微信，點擊微信右下角的我的進入；
3、在我的裡面找到設置並點擊進入找到設置中的通用點擊進入下一步；
4、然後在通用中找到聊天記錄備份點擊進入；
5、然後在點擊菜單中的遷移聊天記錄到另一台設備；
6、然後根據自己的情況選擇遷移，是全部記錄遷移還是部分自己選擇點擊進入下一步；
7、最後在新手機上登陸即將遷移的微信根據原來手機的提示操作就可以了，等幾分鍾備份成功後把舊手機微信退出就可以了，打開新手機上的微信全部聊天記錄都在。
