With the server split, the 100% RCR NPC will go live as well. As a reminder, the 100% RCR period will be “AT YOUR OWN RISK." We are not able to provide staff support for it, as was originally stated by Zanniej in this post: viewtopic.php?f=10&t=74769.
It is strongly recommended that you wait a couple more weeks before you try to RCR, while we ensure that the new server and databases are stable. The RCR period will likely remain in place for at least a couple of months, so do not feel like you have to rush to do one while server stability is still being tested. We will announce it at least two weeks in advance before turning off the 100% RCR period.
Additionally, please be aware that if we run into significant problems with the split or with the update, then there may be a need to rollback the server update and, or, server character vaults. We do not expect this to occur, and the new system has been heavily tested, but if it is required then there is the possibility that you could lose any mechanical progress you make this weekend (XP, items, trades, GP, etc.).
Many people helped with the server split -- with development, with idea generation, with testing, with deployment -- and there were numerous hurdles along the way, such as ensuring that players on server 1 could send Tells to players on server 2 and vice-versa. But your development and QC teams crushed all of these obstacles. As such, the admin team would like to thank everyone who was involved in and worked on this project for their many, many hours of labor. You all made this possible.
The following Q&A, courtesy of Ewe, should help answer some of the basic questions you might have about the server split:
