How to Find the unique rendering ID for a placeholder

Question

We are currently upgrading a site from 8X to 10.2. We are trying to change the dynamic placeholders as per 10.2. But 8.2 dynamic placeholders are of format-

/a/b_1/c_1, /a/b_1/c_2, /a/b_2/c_3.

We found that when manually adding rendering to dynamic placeholder in 10.2, the placeholder format is /a/b-{UID-a}-0/c-{UID-b}-0. How to find the UID of a or b either in Powershell or C# if more than one "a" or "b" is present in Final Rendering XML? Please refer above snippet of our 8.2 placeholder pattern

Go through utility: https://github.com/rishishekhawat/FixDynamicPlaceholders , i hope it should help you.

Here you can utilize the code, you can see highlighted area, it is not dependent on old UID, for reference giving code below as well:

 foreach (RenderingDefinition rendering in device.Renderings)
                {
                    if (!string.IsNullOrWhiteSpace(rendering.Placeholder))
                    {
                        var newPlaceholder = rendering.Placeholder;
                        foreach (Match match in Regex.Matches(newPlaceholder, PlaceholderRegex, RegexOptions.IgnoreCase))
                        {
                            var renderingId = match.Value;
                            var newRenderingId = "-{" + renderingId.ToUpper().Substring(1) + "}-0";

                            newPlaceholder = newPlaceholder.Replace(match.Value, newRenderingId);

                            requiresUpdate = true;
                        }

                        result.Add(new KeyValuePair<string, string>(rendering.Placeholder, newPlaceholder));
                        rendering.Placeholder = newPlaceholder;
                    }
                }

Hope it will help...
