Multi DB Plugin Replacement

Hi, I am currently using Multi DB plugin from WPMUDEV which is no longer supported. After updating WP to latest version it required updating MySQL and PHP, which resulted in tons of errors from the Multi DB plugin – so I am looking for a replacement. I have a multisite/multinetwork installation and currently use 17 databases (1 for Global and 16 for individual blogs labelled 0-9 and a-f. The Multi DB plugin uses a MD5 hash to determine what database for each blog. It uses the first character of the MD5 hash of the blog ID as the db for that blog. For example: Blog ID: 832 832 Hash: 7250eb93b3c18cc9daa29cf58af7a004 First Character: 7 The blog is in db 7. Does your plugin use a similar logic for distributing multisite blogs or is it configurable to do it in this manner? The more obvious question; could I use your plugin to replace my existing one and how complex would the transition be? Thanks, Pat
