Hi. We’re slowly migrating from 5.1.73 to 5.7.29 (and then later to 8, but need an intermediate step for compatibility).
Is there a toolkit version which supports both, or are all the toolkit versions backwards compatible for older versions of mysql, I can’t dig out that info anywhere.
Mainly we want to update some fields without locking, so hoping pt-online-schema-change will be working for those versions ?
Thanks in advance.
