Impacts of CDC when patching SQL server #1942
Conversation
Add a topic about impacts of CDC when patching instance. If instance enters on script upgrade mode, it will runs proc sp_vupgrade_replication, which runs sp_cdc_vupgrade. In this proc, it can rebuild indexes. I wokred on company that experinced this problem in SQL Server 2008 R2, and after talking with support, it was fixed, but current code (checked on version 2016), can trigger these rebuilds yet. BEcause this, i guess is important alert readers for they plan instance patching.

Hey @rothja, the merge was made and this change is on live branch, but not in the page. What is the frequency the page get synced with live branch? |

@rrg92 Thanks for the follow-up. We had a very rare publishing freeze last week. It is lifted today, and I expect you'll see the changes by tomorrow morning at the latest. Normally, public PRs go through in about 24 hours after they are merged in. Thanks! |
