As I read in Embedded memory user guide, "Read old data during write" is not supported in M10K and M20K blocks. Since Cyclone V device has only M10K blocks, can I assume that "Read old data during write" is not possible in Cyclone V? If yes, what is the alternate solution for this? Looking forward for help.. Thanks.

From what I read it is allowed in cyclone V for certain memory types (single clock or dual...). If in your case it is not allowed then check that you do really mean to read old data & write.
If that is required by your design then you could change your plan and read just before write by delaying write on same address.
