在laravel中，如何将A数据库的表A复制到B数据库的表B

先上代码

今天一个老哥来找我帮他修改一下代码，真是活久见，看到上面的代码，人都是傻了，整体看了下他的大概功能是：
【将A数据库的表A 复制到B数据库的表B】
这是以前一个哥们写的代码，超级好奇他是怎么把这么多的字段全部抄下来的
他这么做的目的只是为了凑出一条条sql语句出来，然后连接另外一个数据，在不断的循环插入到B数据库中，如果是你，你会怎么办？

说说我的想法吧

方案1

如果是由于各种原因，需要将老的表重新切换到新的表中，新旧表字段可能无法对应起来情况下：
a:将旧表直接修改表结构为新表的结构，新表替换旧表。

方案2

如何旧表依然需要，但是旧表产生的数据需要同步到新表
a:当curd数据的时候，异步创建一个队列自动同步到新表中，这样就可以避免写大量的for循环。

你们有什么好的方案呢？
