In my group, everything has migrated to a single version. Two months have passed since the first problem with synchronization appeared. Now everyone can see each other's files and folders on their computers. But the problems with the transition are not only in the visibility of folders, I will try to list what I encountered:
- when the problem appeared, at the beginning of the migration of the first group member, some of the latest changes in the files were lost. Although they were saved in the file versions. I had to restore them manually.
- It is a big problem to download back all the deleted files from the computer, especially if this is measured in tens of gigabytes. The computer completely falls out of working order for several days, since everything slows down sharply when OneDrive is actively working. I can't even imagine who had to restore hundreds of gigabytes of data, or even terabytes.
- After reverse synchronization, different users had similar folders with domains that differed by the computer name. The folders contained a similar set of files, but the files could differ in content if they were edited on different computers. It was necessary to bring everything back together.
On the useful side, I can say that I have greatly lost confidence in Microsoft and realized that you can't relax, no clouds will protect you from data loss, rather the opposite, you can lose everything and everywhere in one moment. If you need to keep something, do it yourself. I wish good luck to everyone who is waiting for the happy moment of completing the migration. I hope that it will come to you soon. Of course, this is not the way to treat users, we have encountered yet another confirmation that all these slogans of companies about caring for customers, improvements for our safety or our convenience are worth nothing, but in fact they simply allow companies to pump more money out of customers.
