search and replace serialized strings in BB

always tail slappin’ fun with BB… until… trying to do a search and replace… can’t seem to find simple solution to running a find and replace for content in BB editor

I ran WP Migrate DB and it worked but it literally took two hours and running through every table in every site on my multisite network… I saw another legacy forum thread about a tool to upload outside of WP which is not practical either.

I can run mySQL queries… but I need something regular admin users can deal with…

any tips on a search and replace plugin that will do the job?

thanks
