In high-load systems there can be issues where one need to import data to collection xxx and then rename it to yyy that currently works on production server.

No, there are no ability to rename collections now

Hi, found the way to do this via executeCommand, e.g.:

$collection->getDatabase()->executeCommand([
                    'renameCollection' => NearestCities::DB_CITIES . '.' . NearestCities::NEAREST_CITIES_X,
                    'to' => NearestCities::DB_CITIES . '.' . NearestCities::NEAREST_CITIES,
                    'dropTarget' => true]);

thing to note here is that u should run this command in admin db context, then it will work properly.

I've sincerely wanted to make a PR, but the problem is that I'm getting the same error on different platforms - MacOS/Ubuntu: PHP Fatal error: Class 'MongoException' not found in /var/sites/php-mongo/src/Exception.php on line 17

My settings for mongodb in php is:

/etc/php/7.1/cli/conf.d/20-mongodb.ini,
mongodb
libmongoc bundled version => 1.8.2
libmongoc SSL => enabled
libmongoc SSL library => OpenSSL
libmongoc crypto => enabled
libmongoc crypto library => libcrypto
libmongoc crypto system profile => disabled
libmongoc SASL => enabled
mongodb.debug => no value => no value
PWD => /var/sites/php-mongo/tests
OLDPWD => /var/sites/php-mongo
$_SERVER['PWD'] => /var/sites/php-mongo/tests
$_SERVER['OLDPWD'] => /var/sites/php-mongo

As u can c I'm using php7.1, probably this is the problem (backward compatibility support by your lib).

You need compatibility layer for php > 7.0. See https://github.com/sokil/php-mongo/blob/master/README.md#installation.
