Switzerland property consultation

Due to the fact that it has become more difficult for Russians to maintain real estate in other countries, is an exchange option possible? For example, I live in Europe, I have real estate in Russia and I want to change my apartment to European real estate. Are there any such options? How much is it really possible to do from the point of view of legality?

Please confirm or deny the following: if the buyer / seller of the property has acquired it as a foreigner under the quota system, a new permit will not be required and the purchase will not be included in the quota set for this year. Details: Real estate in the canton of Bern belongs to the Russian, as a mortgage with the bank for a mortgage. Acquired more than 5 years ago. When buying, you get a quota and the necessary permits. When selling to a non-resident in Switzerland, is there a new quota for the purchase of this property?
