# Odarhom FAQ ❔

### **WARNING 🚧** <a href="#wiki_warning" id="wiki_warning"></a>

Wallets created in version 0.90.8.x and later are not compatible with versions prior to 0.9.8.x and will not work if you try to use newly created wallets in older versions. Existing wallets that were created with older versions are not affected by this.

Use only the official releases from [GitHub](https://github.com/LIMXTEC/BitCore/releases/latest)!

### **COMPATIBILITY**  <a href="#wiki_compatibility" id="wiki_compatibility"></a>

Odarhom Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, Windows 7 and later and should also work on most other Unix-like systems but is not frequently tested on them.

The first time you run version 0.9.8.x or newer, your chainstate database will be converted to a new format, which will take anywhere from a few minutes to half an hour, depending on the speed of your machine.

**We strictly recommend to remove the folder "chainstate" and "blocks". Do not touch or remove your wallet.dat.**\
In some cases there were unforeseen error messages insofar as they did not completely new synchronize the old chain.

You can also just replace the local blockchain with the [zip](https://github.com/LIMXTEC/BitCore/releases).
