You'll not get any problem if you flash a proper rom on your device for upgrading, but backing up the efs is always advised.

Flash your proper official rom (Download it from Sammobile.com or Sampro.pl), After flashing, go directly to Recovery menu (By pressing Vol up + Menu and then Power key) and hit >>"Wipe data and cache"<< it'd get your IMEI back.
