Best way to search and replace text from blocks Is there a module or some other method to find and replace text from all existing blocks?  I've come accross Search and Replace Scanner Module but it looks like it only does search and replace on nodes.  

Much Thanks.
Are you referring to custom blocks, not those provided by modules? If so, the main data is in the body column of the block_custom table in MySQL.

You could use an SQL query to perform the replacement.

UPDATE `block_custom` SET `body` = replace(body,"findstring","replacestring");
