We have a “trigger” rules to start the sync that is working but once the initial sync is established… subsequent syncs will happen regardless of the condition… we only want sync (after initial sync) only to happen if certain condition is met… how can we do that?

Hi Samip,

In the incoming script of your destination side, you can have some logic right after the “if (firstSync)” block, so that it “returns” aka does nothing if a condition isn’t met, for example, if your condition was that the priority must be “1-High” you can have something like:

```auto
if (replica.priority != "1-High") {
	return;
}

```

And after this, you can have all your normal sync rules, so if the condition is met, it goes through your normal sync rules, but if it isn’t, it does nothing.

Let me know if this is a solution for you.

Thanks,

André
