Ask a master who knows Feng Shui. Recently, my brother's relatives wanted to change the grave for grandpa's father. When they went to the fief, they suddenly had a vision. Ask.
Secondly, I'll tell you a few things about moving graves. First, those with purple breath can't move, which is auspicious land. Second, living things such as turtles and snakes can be found in the soil, so they can't move. This place is not full of soil fertility, and there are too many variables to move without authorization, so the new place may not be as good as the old one. Third, the plants around the graveyard are so lush that they can't be moved. Such a place is rich in soil fertility and favored by the ancestors' souls. If it is moved without authorization, it will be harmful and not beneficial.
Let's talk about the vision you mentioned. If the vision doesn't have a tendency to hurt people and things, it's good, which proves that the ancestors just don't want to leave here. If the vision hurts anything, even a tree and grass, it's a big deal. You must find a master-level person to help move the grave, and move it anyway, otherwise the consequences will be unimaginable. I won't say the details.
I started at the age of 16. Although I have never been out of the mountains, I have also run over 2 mountains and seen more than 1 places. I hope it will help you!
