There is no migration after the Conquest (of Mecca), but Jihad and sincere intention. When you are asked to set out (for the cause of Islam), you should set out,  

سُئِلَ رَسُولُ اللَّهِ ﷺ عَنِ الْهِجْرَةِ فَقَالَ: «لاَ هِجْرَةَ بَعْدَ الْفَتْحِ، وَلَكِنْ جِهَادٌ وَنِيَّةٌ، وَإِذَا اسْتُنْفِرْتُمْ فَانْفِرُوا۔»  

the Messenger of Allah ﷺ prohibited mutʿah (temporary/pleasure) marriage in the year of the conquest ˹of Makkah.˺  

نَهَى رَسُولُ اللهِ ﷺ عَنْ نِكَاحِ الْمُتْعَةِ عَامَ الْفَتْحِ  

“You will conquer Constantinople three times: (1) the first time, you shall be tested heavily; (2) the second time, there will be truce between you and them ˹until you build a mosque in their city and you and they will battle as enemies behind Constantinople:˺ and (3) as for the third time, Allah will help you conquer it with takbīrs: then Allah will destruct a third of it, burn a third of it, and divide the remaining third in measures.”  

"إِنَّكُمْ سَتَغْزُونَ القَسْطَنْطِينيةَ ثَلاَثَ غَزَوَاتٍ، الأولَى: يُصيبُكُمْ فيهَا بَلاَءٌ، وَالثانِيةُ: يَكُونُ بَيْنَكُمْ وَبَيْنَهُمْ صُلح (حَتَّى تَبْنُوا فِى مَدينَتِهِمْ مَسْجدًا، وَتَغْزُونَ أنْتُمْ وَهُمْ عَدُوًا وَرَاءَ القُسْطَنْطِينِيَّةِ)، وَأمَّا الثَّالِثَةُ! فَيَفْتَحُهَا الله علَيكمْ بِالتَّكْبيرَات، فَيُخَرِّبُ اللهُ ثُلُثَهَا ويحرق الله ثلثها، وَتَقْتَسمُوَنَ الثُّلُثَ البَاقِىَ كيْلًا".
