游走 only means "migrate" in a specialized (medical) sense, namely, in reference to the migration of organs in the body, as in "floating kidney". 【https://baike.baidu.com/item/%E6%B8%B8%E8%B5%B0%E8%82%BE】 However, the full form of that word almost always uses 遊 rather than 游 (遊走腎, not 游走腎). (See Google results below.) E.g. 遊走腎（Nephroptosis或Floating Kidney）是指當體位從臥姿變為立姿時，腎臟的位置從原來後腹腔相當高位的 “腎窩”（renal fossa）明顯的往下滑落。 I will put in a submission for an entry with 遊走 as the full form of the headword.
Google results (using the 'verbatim' option):
"遊走腎" - 96,800 results
"游走腎" - 1,130 results
But this entry for 游走 can be retained since 游走 (both full form and simple form) means "swim away". Examples:
還欺騙子產說那條魚放在池中，一下子便開心地游走了，
「才抵達第一天，就把我二十幾年來想拍攝的畫面全部拍到了，真的很感動，還記得當下自己問自己，這是真的嗎，夢想成真了嗎？……雖然很想更仔細的端詳牠，但還是提醒自己是來工作的，即使是幻境，也要立刻用攝影機翔實記錄，就怕牠很快又游走了。」 (牠 here refers to a humpback whale)
