We recently upgraded to V12.1 at the beginning of June. Last week I ran the Migrate Wiki to Article Collection overnight in a group with just under 1,000 wikis.
The utility failed at around 70% with an "Unknown Error - Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
The end result - We have a full collection of both wikis and matching articles. Both now show in search. The utility never finished creating the url redirects - which is critical for us - or deleting out the wikis.
Has any run into this before? Debating if I should run the utility again hope it will pick up where it left off completing the process or if I should delete out the entire article library and start the utility again from scratch.
