By way of a quick intro, I am new to the WordPress forum but not new to WordPress. After looking through the other forum topic lists, I thought this would be the single best place to post this question. (I am not using MU, but have many multiple sites.) Please forgive a new registration doing an opening post, but this seemed the best place.
I very much need any and all recommendations for any type of software designed to deal with multiple WordPress sites. Upgrades have become rather time-consuming. When a new version comes out, I load an Excel spreadsheet of user names and passwords and manually go into each site for upgrading versions and plugins. Back when I only had a few dozen sites installed, that was manageable.
It is likely I am just not using the proper keywords to get useful SERPs with selections of software for this purpose. I tried looking for WordPress site managers, WordPress password software, WP user management, etc. - a number of other search phrases, and also ran those searches against this forum's posts.
After several hours of this, a couple of potentially useful results were returned, but did not address preferred features. One was a monthly subscription, which I don't do. One was designed for doing mass installs. One login manager was a plugin that tracked updates through a MU site - that one made me paranoid about installing something like that on the servers.
Does anyone here know of a Windows application designed to manage multiple WordPress installations? ...code that can be trusted with site passwords? Tracking users and passwords is a must, version tracking of a database of plugins by site would be a help, site modification changes by date would be a plus, something that is from a trusted publisher that could be password protected is vital. Preference is for a paid commercial product that stores all data on my computer, and has no code on the servers.
Thank you for any and all assistance you may be able to provide, Ken
P.S. Also, if anyone knows of any books or other software that can help with maintenance of large quantities of sites, that would also be quite helpful :~)
