I can only call it a weekly diary... Make a week's summary.

Summary: Migrating servers is a real hard job.

On Monday, server data backup will be performed.
On Tuesday, we started installing new machines, configuring, importing data, and debugging.
On Wednesday, the official shutdown and relocation.
On Thursday, I finally got it started with great difficulty, and I suddenly realized that there was something wrong with the machine... I could only repeat the work again...
Friday, finish, permissions are set. Check data integrity. Sure enough, during the transfer, a small part of the data was inevitably lost.
On Saturday, a colleague returned to the Hubei company and was Happy until late into the night.
On Sunday, a partner came from far away and picked up the train at the railway station in the early morning. Then "accompany" three times until noon the next day.
