Basic misunderstanding, you coins are always values contained on the BTC blockchain. Your wallet only keeps the keys and reports what is on the blockchain for those keys/addresses. The private key allows you to create a transaction for the blockchain that the miners will approve. So you do not need to move anything anywhere to use a new wallet.
omni-assets are stored in the BTC blockchain so the above applies to them.
You should see MAID for the address you imported the private key to.[quote=“1492, post:7, topic:12851”]
The private key is in WIF format. Doing some brief research I thought I saw a WIF key should start with a 5, but mine doesn’t. I also saw something about needing to do something to convert a private key in WIF format.

That would suggest that you didn’t import the private successfully. Although the omniwallet should not be showing the address then. (unless it is a watch only address)
There is another topic here that discusses the issues with importing private keys. Omni-wallet can only import private keys starting with “5” even though it says it can do more.
