EDIT: Migration Postponed:
Because there was too many errors that wasn't resolved on time for migration, it was postponed to later this week. After all issues will be resolved on the new client.
There are 7 issues that still need to be resolved before migration.

Migration Update PLANNED 28.12.2025:
Date: Planned for next Sunday, assuming no further crashes occur on the test server.
Auctions: Website auctions are disabled (items will be returned). Character auctions will be disabled starting tomorrow.
Disabled Features: Lottery and raids will be disabled or limited at launch due to crash issues.
Website: As we move to the new site, some web functionalities will be unavailable prior to the full migration.
Houses: There will be no house cleaning yet.
Mounts: Mounts are enabled, but monster drops for mount items (e.g., Bag of Apple Slices) are currently disabled.
Delays: If critical bugs appear, we will delay. I want to avoid irreversible database damage that would force a rollback.

I rather avoid rushing migration to new client and new engine if that would cause changes that cannot be reversed.
If on sunday everything will be ready, migration may take some time - possibly few hours of downtime.
